Need to start up a new to setup special registers use
`arm_pic_setupxcp`.
Note that CONFIG_BUILD_PIC compiles the entire NuttX image
as position-independent(PIC), enable CONFIG_PIC to load PIC
application code.

The default heap management in nuttx returns a valid memory address when malloc(0).
In sim_heap, malloc(0) returns NULL, aligning the behavior of sim_heap with mm_heap
The man manual describes malloc as follows:
https://man7.org/linux/man-pages/man3/malloc.3.html
The malloc() function allocates size bytes and returns a pointer
to the allocated memory. The memory is not initialized. If size
is 0, then malloc() returns a unique pointer value that can later
be successfully passed to free(). (See "Nonportable behavior"
for portability issues.)

Added a flash driver for the STM32G4 series. The primary change here is
the addition of stm32g4xxx_flash.c. This file uses the STM32L4 flash
driver as a template. The primary difference is the accounting for dual
banks with different page sizes.
Fixed error while building b-g474e-dpow1/buckboost. It was possible (technically) to have page be used uninitialzied. Changing the if statement to default to using a flash_page_size == 2048 fixes this issue.
In armv8m the FPSCR[18:16] LTPSIZE field must be set to 0b100 for
"Tail predication not applied" as it's reset value.
