Align with mainline BSP and fix relevant bugs:
1. Align with SPI module naming
(1) Remove SPI5
(2) Degrade QSPI0 to SPI4 so that it can use for standard SPI
2. Fix some code lacking GPIO H
3. Implement __PC(...) by following BSP instead of with MBED_CALLER_ADDR()
4. Add SCU_IRQHandler(). Change printf(...) with interrupt-safe error(...)
5. Other minor alignment change
RAM/ROM sizes in tools were updated to report entire device size, and in M2351
they were used earlier to report secure/non-secure partition size.
M2351 files are updated to take full RAM/ROM device size and derive secure
and non-secure partition size based on that.
To change TRNG security state, we need to:
1. Change CRPT/CRYPTO bit in NVIC/SCU in partition_M2351.h
2. Add/remove TRNG in device_has list in targets.json to match partition_M2351.h
NSC location has the following requirements:
1. By IDAU, 0~0x4000 is secure. NSC can only locate in 0x4000~0x10000000.
2. Greentea flash IAP uses last 4 sectors for its test. Avoid this range.
3. Greentea NVSTORE uses last 2 sectors or 4KB x 2 for its test. Avoid this range.
All modules are configured to non-secure except:
1. TIMER0/1 hard-wired to secure and TIMER2/3 reserved for non-secure.
2. PDMA0 hard-wired to secure and PDMA1 reserved for non-secure.
3. RTC configured to secure and shared to non-secure through NSC.
4. CRYPTO configured to secure and shared to non-secure through NSC.
As per SAU documents, SAU is always present if the security extension is
available. The functionality differs if the SAU contains SAU regions.
If SAU regions are available it is configured with the macro __SAUREGION_PRESENT
