Even when enabled, the PCNT counter doesn't accumulate into the 32-bit value.
Instead, a value in range [PCNT_LOW_LIMIT, PCNT_HIGH_LIMIT] is always returned.
This is due to interrupt events associated with limit overflows are disabled on the periphery,
therefore the ISR responsible for the accumulation never gets called.
Fixed by enabling the associated interrupt events.

- Standardized the cache terminology, changing "D-cache" and "I-cache" to "Dcache" and "Icache" for consistency with existing code style.

This term is used by NXP's ROMAPI naming conventions and is not a typo
in this context.

MMU initialization is redundant for bootloaders(BL2) that load TF‑A(BL31).
TF-A will ignore and overwrite any MMU configuration performed by BL2.
Additionally the MMU comes with a large memory footprint (~50 KB)
which could be precious for such setups.
When the MMU is disabled all the memory is treated as device memory and
all alignment faults generate exceptions (as opposed to normal memory when
MMU is enabled). For that reason we need to add -fno-builtin when compiling
with CONFIG_ARCH_USE_MMU != y to prevent alignment faults.
- Guard MMU initialization with CONFIG_ARCH_USE_MMU
- If CONFIG_ARCH_USE_MMU is not set add -fno-builtin which prevents alignment errors.
- Deliberately didn't try to replace CONFIG_ARCH_HAVE_MMU with CONFIG_ARCH_USE_MMU
occurrences, because this will break a lot of build targets that assume MMU without
guarding the MMU initialization.

This adds support for the i.MX9 ROMAPI, allowing boot in a more
device agnostic and portable manner. The ROMAPI "natively" allows to:
- Query the boot device for information.
- Copy data from the boot device to RAM.
An extra functionality was added to ROMAPI to calculate
offsets of sequential AHAB containers.
The AHAB functionality is built on top of raw ELE primitives and allows to:
- Authenticate a container image.
- Release the authenticated container.

So far NuttX has supported OP-TEE interfacing over
local and RPMsg sockets. This commit introduces support
for direct invocation of OP-TEE through arm SMCs. The
SMC transport is enabled through CONFIG_DEV_OPTEE_SMC.
This SMC implementation has been tested only with arm64,
OP-TEE rev 4.4.
Note that it does not support reverse direction RPCs,
i.e. from the Secure World to the Normal World to
something like optee supplicant. A basic RPC handling
skeleton is provided with implementation for some
basic functions (alloc/free mem, and foreign interrupts)
but no supplicant command handling.
(+one minor change s/parm/param in arch/arm64/include/syscall
to satisfy the spellchecker during PR)

This patch adds definitions for listed chips. No other changes are needed
as the chips are similar to the previously supported AVR128DA28 and all
that is needed is some definitions for extra peripherals.
AVR DA/DB family chips have single interrupt vector for all changes
on an I/O port. This poses problem when multiple drivers want to claim
the same interrupt (might happen for example with button and discrete
joystick drivers using pins on the same port.)
The I/O multiplexer solves it by providing interface similar
to irq_attach. However, it allows registration of multiple handlers
for the same interrupt vector with additional information recording
which pins should be serviced by each handler.
Only handler for pins that triggered the interrupt is then called.
Initial support adds chip specific files like Kconfig, flags for the compiler,
and basic functionality like system timer. Some files are stubs derived
from corresponding ATmega files but without the functionality they are
supposed to add (to be done in later patches)
Part of the work is altered copies of corresponding files for ATMega MCUs.
Initially supported is AVR128DA28.
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

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.
