[ARM] 4784/1: S3C24XX: Fix GPIO restore glitches

Browse source

The core resume code may have caused glitches in the GPIO when
restoring the GPIO state due to the order in which the GPIO registers
were being written.

Change the restore process take into account the state of the
GPIOs on resume and the state the system wants to restore them to.

See the code comments in the patch for more details of the process.
