Chun-Chieh Li 967effe59f [M252KG] Free up peripheral pins in peripheral free-up HAL API
Without free-up of peripheral pins, peripheral pins of the same peripheral may
share by multiple ports after port iteration, and this peripheral may fail with
pin interference.

Chun-Chieh Li 1447d9049f [M252KG] Fix redundant call to UART IRQ handler
Honor RxIrq/TxIrq to avoid redundant call to UART IRQ handler.

This is also to fix FPGA CI test mbed_hal_fpga_ci_test_shield-uart.

Chun-Chieh Li 0917a0d5a6 [M252KG] Fix IP initialization sequence
Better IP initialization sequence:
1. Configure IP pins
2. Select IP clock source and then enable it
3. Reset the IP (SYS_ResetModule)

NOTE1: IP reset takes effect regardless of IP clock. So it doesn't matter if
       IP clock enable is before IP reset.
NOTE2: Non-configured pins may disturb IP's state, so IP pinout first and then
       IP reset.
NOTE3: IP reset at the end of IP initialization sequence can cover unexpected
       situation.
