[PATCH 2/4] pinctrl: amd: Fix mistake in handling clearing pins at startup

[Mario Limonciello <mario.limonciello@amd.com>]

commit 4e5a04be88fe ("pinctrl: amd: disable and mask interrupts on probe")
had a mistake in loop iteration 63 that it would clear offset 0xFC instead
of 0x100.  Offset 0xFC is actually `WAKE_INT_MASTER_REG`.  This was
clearing bits 13 and 15 from the register which significantly changed the
expected handling for some platforms for GPIO0.
