Relevant modifications:
1. Support degrading QSPI0/1 to SPI4/5 for normal SPI transfer
2. Fix with BSP crypto driver API change
3. Fix with BSP PDMA driver API change
4. Make necessary modifications to pass FPGA CI Test Shield tests
5. Don't distinguish pinmap among parts e.g. M480 LG. Application users must take care.
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
