[SRU Z/A] [PATCH 0/2] Fix interrupt storm caused by pinctrl-amd on Gigabyte boards

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1671360

[Impact]
pinctrl-amd on Gigabyte AM4 boards generate interrupt storms, makes the system
unable to boot.

[Fix]
Commit "pinctrl: amd: make use of raw_spinlock variants" is to make another
commit a clean cherrypick.
Commit "pinctrl/amd: Use regular interrupt instead of chained" from
linux-gpio/fixes can fix the issue. It changes the chained interrupt to regular
interrupt.

[Test Case]
User reported it does fix the issue in comment #170.
