soc/amd/stoneyridge: Add functions for GPIO interrupts
Add a function to configure interrupt settings for a GPIO. This does
not currently configure GEVENT signals.
The second function returns the GPIO interrupt status and clears the
flag if set.
BUG=b:72838769
BRANCH=none
TEST=Update and test interrupt settings for GPIO_9 on grunt
