[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.
