mb/google/nissa: Skip locking for GPP_F14 GPIO

There is an existing issue for nissa boards where wake up from
RTC wake is not working during suspend_stress_test.

This issue was root caused to the patch which was setting GPE_EN
bits for the GPIOs before locking.
Reference: https://review.coreboot.org/c/coreboot/+/64089

Later issue was found to be with GPP_F14 configuration for nissa
boards. When coreboot skips setting GPE_EN bit for GPP_F14, RTC
wake works properly. Another way to make it work is to skip locking
GPP_F14 GPIO to allow kernel to configure it properly.

This patch skips the locking for GPP_F14 to allow kernel to
configure it later. This fixes the issue of RTC wake not working.

Note: This patch provides workaround for the existing issue and
BUG will be closed once actual reason is identified and proper
fix is available.

BUG=b:234097956
BRANCH=None
TEST=RTC wake works on Nivviks board with the patch.
