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.

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.
