Rename STM32_IRQ_NEXTINT to STM32_IRQ_NEXTINTS across all stm32
variants.

registers based on STM32_IRQ_NEXTINTS.
Use PRIx32 format specifier instead of 'x' (since uint32_t on arm is

Added subclasses of STM32G0 (such as STM32G07X) to Kconfig for use in dmamux driver. Added definitions to stm32g0_dmamux.h. Added configuration of number of dma and dmamux channels.
Added missing dma mappings for stm32g0.
Remove reserved defines.
Formatting fixes.
Added DMA2 IRQ mappings for STM32G0B and STM32G0C. Changed STM32_DMAMUX_BASE to STM32_DMAMUX1_BASE to align with stm32_dma_v1mux.c and C0 defines.
Provide correct mapping for ADC1_DMA_CHAN. Add STM32F0L0G0_HAVE_ADC1_DMA to STM32G0.
Add support for continuous mode to the ADC. Also added support to set smp1 and smp2 in board.h, as well as smpsel.
Removed unnecessary selects of STM32F0L0G0_STM32G0. Changed board level files to properly define A0-A3 on nucleo-g0b1re.
Add new Kconfig changes.
Made combined configs for STM32G0. Ex. STM32G0BX for STM32G0B0 and STM32G0B1.
Fixed defines and references in Kconfig and stm32_dma_v1mux.c
Defined adc_sampletime_write and adc_sampletime_set. Changed adc_sample_time_s structure to be much simpler. Old way made no sense. You can only have 2 sample times, so defining one for each channel makes no sense. The new adc_sample_time_s contains smp1, smp2, and smpsel. Also define ADC_HAVE_SMPR_SMP2 for STM32C0.
Added adc_sampletime_write and adc_sampletime_set. Altered adc_sample_time_s structure to be more appropriate for g0 and c0. Only two sample times can be defined. Added rcc support for DMA2.
Added defconfig for nucleo-g0b1re:adc_dma config.
Restore correct Kconfig from my original branch
Removed redundant ifdefs. If we select for G0 and C0, we know they have SMP2. Fixed formatting.
Formatting feedback. Aligned columns in irq and dma headers.
The l1entry replace cause huge time when text/data is big,
Need 16KB per task to hold l1table.
Also critical_section no longer required, as table per-task maintained.

Squashing lots of define errors to get ethernet.c working
quick path rename
Fix STM32_EMAC_BASE (and ICACHE/DCACHE Bases). Enable ETH, ETHTX, and ETHRX with CONFIG_STM32H5_ETHMAC (like H7 does).
Fixed stm32_get_uniqueid
Previously, an exception occurred as a result of calling this function. The problem turned out to be this line: uniqueid[i] = *((uint8_t *)(STM32_SYSMEM_UID) + i);. Dereferencing a 32-bit register as a 8-bit register seemed to be causing this issue. I think this function is better anyway, fewer register accesses and loop iterations.
Turn on SBS peripheral when using Ethernet
The SBS peripheral is required to be turned on because the ETH_SEL_PHY bits need to be set. Without turning this on, RMII mode is not possible. MII may not work either.
Style Updates
Inline & inline_function both used make confuze, let's modify all inline
in irq.h to inline_function, also clear the always_inline_funcion
declaration.

reason:
svc call may trigger hardfault
Background
The origin of this issue is our desire to eliminate the function of storing
"regs" in g_current_regs and instead utilize (*running_task)->xcp.regs for storage.
The benefits of this approach include faster storage speed and
avoiding multiple accesses to g_current_regs during context switching,
thus ensuring that whether returning from an interrupt or an exception,
we consistently use this_task()->xcp.regs
Issue Encountered
However, when storing registers, we must ensure that (running_task)->xcp.regs is invalid
so that it can be safely overwritten.
According to the existing logic, the only scenario where (running_task)->xcp.regs
is valid is during restore_context. We must accurately identify this scenario.
Initially, we used the condition (running_task)==NULL for this purpose, but we deemed
this approach unsatisfactory as it did not align well with the actual logic.
(running_task) should not be NULL. Consequently, we adopted other arch-specific methods for judgment,
but due to special logic in some arch, the judgment was not accurate, leading to this issue.
Solution:
For armv6-m, we haven't found a more suitable solution, so we are sticking with (*running_task)==NULL.
For armv7-m/armv8-m, by removing support for primask, we can achieve accurate judgment.
PRIMASK is a design in armv6-m, that's why arm introduce BASEPRI from armv7-m.
It's wrong to provide this option for armv7-m/armv8-m arch.

This is continue work of https://github.com/apache/nuttx/pull/13726
We can utilize percpu storage to hold information about the
current running task. If we intend to implement this feature, we would
need to define two macros that help us manage this percpu information
effectively.
up_this_task: This macro is designed to read the contents of the percpu
register to retrieve information about the current
running task.This allows us to quickly access
task-specific data without having to disable interrupts,
access global variables and obtain the current cpu index.
up_update_task: This macro is responsible for updating the contents of
the percpu register.It is typically called during
initialization or when a context switch occurs to ensure
that the percpu register reflects the information of the
newly running task.
