mb/google/nissa/var/anraggar: Skip locking for GPP_F15 GPIO
There is an existing issue for Anraggar where wake up from
RTC wake is not working during suspend_stress_test.
The phenomenon of the issue is that after pulling out the
stylus, can see an interrupt storm occurs through
"cat /proc/interrupts | grep acpi".
When the counter of interrupts is greater than a certain
value, "Disabling IRQ #9" will occur, so RTC wake is not
working.
Reference: https://review.coreboot.org/c/coreboot/+/65086
This patch skips the locking for GPP_F15 to allow kernel to
configure it later. The interrupt storm of acpi dispeared.
BUG=b:321348117
TEST=cat /proc/interrupts | grep acpi
There isn't interrupt storm of acpi when pulling out stylus.
Pass suspend_stress_test -c 2500 --suspend_min=15 --suspend_max=20
