amd/stoneyridge: Disable GPIO MASK STATUS
MASK_STATUS disables interrupt status generation for the entire GPIO controller when any debounce register is configured. This causes problems when the kernel is loading drivers because we could lose interrupts for previously loaded devices. sb_program_gpios is also not setup to wait when configuring PAD_DEBOUNCE, so there is a potential that we could lose the interrupt status enable bit for other registers. By disabling MASK_STATUS we avoid that problem. BUG=b:113880780 BRANCH=none TEST=Ran a reboot stress test that concluded that we are no longer losing TPM interrupts while booting.
