Summary

Mask all interrupts coming from the AMD GPIO controller and service any potential interrupts. Unserviced interrupts can block entry to S0i3 on certain AMD CPUs.

Test Plan

Tested on Phoenix (AMD Framework 7040 series). Can log touchpad interrupts (pin 8) if enabled. Validated masking is enabled by checking for unserviced interrupts (in subsequent patch).
