mb/google/poppy/variant/nocturne: configure SAR irqs to use PLTRST
GPIO's that use GPI_APIC setting with DEEP causes an IRQ storm after
S3 resume. GPIOs that fire IRQs via IOAPIC need to get their logic
reset over PLTRST to prevent IRQ storm after S3 resume and hence
configuring GPP_D9 and GPP_D10 to use PLTRST.
