mb/google/brya/var/agah: Modify GPP_F14 programming
For some yet unknown reason, when this GPIO is locked, there is an
interrupt storm for IRQ #9 apparently caused by GPE 0x66. GPP_F14 is set
to GPE 0x64 on the ADL platform, so this doesn't quite make sense. This
patch removes the lock and fixes this IRQ storm, but the root cause is
not identified yet.
BUG=b:236997604
TEST=`grep ' 9:' /proc/interrupts` shows a reasonable value now
