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.
