Chun-Chieh Li c3d7ef8341 [Nuvoton] 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 d46c6fea47 [Nuvoton] Fix redundant SPI clock generation 
Fix SPI clocks are generated redundantly at the end of transfer.

This is also to fix FPGA CI test mbed_hal_fpga_ci_test_shield-spi/
SPI - async mode.

Chun-Chieh Li fef138a3cd [Nuvoton] 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.

ccli8 7275ee8626 [Nuvoton] Fix SPI DMA transfer 
1. Disable unnecessary TX/RX threshold interrupts to avoid potential trap in DMA transfer
2. Start TX/RX DMA transfer simultaneously to fit H/W spec and avoid potential RX FIFO overflow issue
