mb/google/nissa: make GPP_F17 edge triggered to avoid spamming EC
In nissa platform, we configured GPP_F17 as SCI+APIC to wake the system
and also generate IRQ to the IOAPIC. Currently, we set GPP_F17 to level
triggered and it causes AP (Application Processor) to keep sending
GET_NEXT_EVENT to EC during resume from suspend by connecting AC.
So we change GPP_F17 to edge triggered to avoid this condition.
BUG=b:308716748
TEST=Original failure rate was 7 out of 10 times and it reduced to
0 out of 60 times on six joxer systems.
