cyliangtw ffee35a5c8 Fix NuMaker I2C timeout, 
some H/W timer count is 24 bits only, hardcode 0xffffffff causing
  wrong judgement of timeout as while H/W timer counting overflow.

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 80c21aeff5 [Nuvoton] Fix I2C NACK error 
Fix logic error on replying NACK at the end of transfer.

This is also to fix FPGA CI test mbed_hal_fpga_ci_test_shield-i2c/
i2c - test single byte read i2c API.

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.
