This patch marks host GCC toolchain option with ARCH_TOOLCHAIN_GCC,
enabling various other settings depending on it. One of the enabled
settings is DEBUG_OPT_UNUSED_SECTIONS.
This patch also adjusts compiler and linker flags based on the value
of DEBUG_OPT_UNUSED_SECTIONS so unused sections are removed
On SMP systems we should enable FPU on each core
FPU extenstion support must be enabled on each core as stated on 4.6.5

RP2350 datasheet and upstream pico-sdk suggests higher VCO freq to
better output stability.
Increase the VCO and update PLL divs according to specs and calculation.
Higher VCO freq is more stable, lower VCO freq is more power friendly.
Also it's possible to use 120/6/5 with VCO 1440MHz for USB PLL to even
higher output stability.
USB setup changes from rp2040
Must clear the MAIN_CTRL.PHY_ISO bit at startup and after power down
events.

On the RP2350, the watchdog receives its tick input from the
system-level ticks block, unlike the RP2040, where the watchdog includes
its own tick generator. Enable the TICK blocks, update the watchdog
routines.

The RP2040 chip supports 4 different GPIO interrupt modes. They can be
configured to be used simultaneously, although previously the NuttX
support only allowed one type of interrupt to be enabled per GPIO pin.
This allows up to all four to be selected without changing previous
behaviour.

Add kernel build (target imx93-evk:knsh) to i.MX93 EVK.
This target is preconfigured for use with AHAB boot (see
https://spsdk.readthedocs.io/en/latest/examples/ahab/imx93/imx93_ahab_uboot.html)
as a replacement of U-Boot proper (BL33 at EL2), hence
the load address is set to 0x80200000.

with a fixed seq of 1, which causes ota_get_bootseq() to return ota_0.
The current solution is to directly use the target partition's number (num)
as next_seq to ensure the correct increment logic of seq. Ensure the formula
(seq-1) % OTA_DATA_NUM + OTA_IMG_BOOT_OTA_0 correctly maps to ota_0 or ota_1

To fix a fpu illegal instruction exception due to fcsr have invalid
rounding-mode, restore fcsr/f0~f31 with a random value from stack because fpu
context is not save into stack when mstatus.fs is clean(not dirty).
The number of save/restore fpu context operations is not equal.
In fact, CONFIG_ARCH_LAZYFPU is a performance optimization mechanism aimed at
minimizing the saving and restoring of FPU registers. In some cases, it
may only need to be saved once but must be restored multiple times.
Therefore, this optimization mechanism dictates that saving cannot be
done on the stack; it must be stored at a fixed location(e.g. task
control block buffer), as the stack requires push/pop operations to be
matched.
In case of that CONFIG_ARCH_LAZYFPU is off, save/restore FPU registers
always into stack to avoid the above issues.
