skylake mainboards: Configure gpio PADRSTCFG to PLTRST
With gpio PADRSTCFG set to DEEP & GPIROUTIOXAPIC=1 & PADRSTCFG, causes
IRQ storm after S3 resume. GPIOs that fire IRQs via IOAPIC need to get
their logic reset over pltrst and hence configuring PADRSTCFG to
PLTRST to prevent IRQ strom after S3 resume.
BRANCH=glados
BUG=chrome-os-partner:50536
TEST=Build for kunimitsu and Boot on FAB4, no irq storm observed
after S3 resume.
