mb/google/nissa: Skip GPP_F15 GPIO locking to avoid IRQ storm

There is an existing issue for nissa 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, checking through:
"cat /proc/interrupts | grep acpi".

When the counter of interrupt 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 disappears.

BUG=b:321348117
TEST=1. cat /proc/interrupts | grep acpi
there isn't interrupt storm of acpi when pulling out stylus.
2. The stylus tools panel will pop up when pulling out it.
3. Inserts stylus can wakeup DUT after powerd_dbus_suspend.
4. Passed:
   suspend_stress_test -c 2500 --suspend_min=15 --suspend_max=20
