mb/google/poppy/variant/atlas: config GPP_F10 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_F10 (HP_IRQ_GPIO) to use PLTRST.
