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
On M2351, some spaces like SYS/CLK are hard-wired to secure and cannot change.
To access these spaces from non-secure world, we must provide platform-specific NSC
functions. With TFM introduced, we must synchronize NSC calls into TFM to keep TFM
in sync instead of straight NSC calls. To achieve this goal, we go with the following
approach:
1. Like PSA APIs, enforce locked entry through tfm_ns_lock_dispatch().
2. Run platform-specific secure functions in default secure partition, in which SYS/CLK
spaces have been configured to be accessible.
Fix SPI module index error in modidx_ns_tab table in CLK_SetModuleClock_S().
Need to update secure image for this bugfix.
This is also to fix FPGA CI test mbed_hal_fpga_ci_test_shield-spi/
SPI - init/free test all pins.
1. Rename m2351_stddriver_sup.h/c to stddriver_secure.h/.c for naming consistency
2. Add hal_secure.h to include hal-exported secure functions
3. Change return/argument type in secure functions:
(1) Change int to int32_t
(2) Change PinName to int32_t
(3) Change time_t to int64_t
4. Update secure lib/bin accordingly
