Use uint16_t variables for i2c slave_rx_buffer_size and slave_rx_count
variables. This allows to receive more than 255 bytes in slave mode. The
bytes are received one by one in slave mode so there are no hardware
limitations forcing a 1 byte rx count limit.
The HAL gpio_irq_api stores object IDs, which serve as a form of context
for the dispatch of the interrupt handler in the drivers level
InterruptIn Class. The way this is achieved is that the InterruptIn
Class casts its address to uint32_t, which is stored as the ID.
This results in compilation failure when the size of an object pointer
is greater than uint32_t, for example when building on a PC for unit
testing.
In order to allow Unit Testing of the InterruptIn Class, we replace the
use of uint32_t with uintptr_t (type capable of holding a pointer),
which allows portability and expresses intentions more clearly.
In aid of this latter goal, we also replace the use of the name "id"
with "context", to improve clarity - these are addresses of the context
related to that callback.
By default, HAL functions (HAL_SPI_TransmitReceive_IT/HAL_SPI_Transmit_IT/HAL_SPI_Receive_IT) assume that SPI is disabled between function invocation.
It's needed to set transfer size (CR2 register), that can be modified only if SPI disabled. But `stm32_spi_api.c` keeps SPI enabled after initialization.
This commit adds helper code for STM32H7 (SPI_IP_VERSION_V2) that disables SPI before HAL_SPI_TransmitReceive_IT/HAL_SPI_Transmit_IT/HAL_SPI_Receive_IT
and after end of transaction for HAL API compatibility.
Update SPI logic to process 16 bit words in the same way by sync/async,
3/4 wires modes:
- fix 3-wire synchronous transmission to move 2 or more bytes between buffer and
SPI register per word tarnsmission
- fix 4-wire synchronous transmission to move 2 or more bytes between buffer and
SPI register per word tarnsmission

Fix the following issues in TF-M to avoid emergence in the future:
1. Enable initial stack not located in SRAM bank0
On reset, only SRAM bank0 is enabled. And SRAM bank1/2 will be enabled in immediately following SystemInit().
When initial stack is located in SRAM bank1/2, we will meet trouble because SystemInit() itself needs to use initial stack.
To conquer the dilemma, we add preceding code in front of original Systeminit(), which is responsible for enabling SRAM bank1/2 and guarantees no using initial stack.
2. Fix sector maps of internal/external (SDH) Flash are incompatible, caused by TF-M's MCUboot port.
This is done by adapting external (SDH) Flash sector size to internal Flash's.
3. Enlarge firmware upgrade scratch size. There are two advantages:
(1) Get around MCUboot limit which requires scratch size not smaller than image trailer size
(2) Improve wear leveling for the scratch area
1. In TF-M, enlarge ITS max asset number/size
NOTE: RSA key size is larger
2. In TF-M, enlarge mbedtls dedicated heap
NOTE: RSA algorithm needs more memory.
NOTE: psa_aead_decrypt() (for mbedtls_ssl_read()) needs memory proportional to data size.
