mb/google/poppy/variant/nocturne: add EC_SYNC_GPIO

Setup EC_PCH_ARCORE_INT_L, tied to GPP_D17, and define as EC_SYNC_GPIO..

 - change GPP_D17 definition to PAD_CFG_GPI_APIC_INVERT as
   EC_PCH_ARCORE_INT_L is active low

 - add EC_SYNC_GPIO to the group of chromeos_gpios for use by depthcharge

BUG=b:139384979
BRANCH=none
TEST="emerge_nocturne coreboot depthcharge chromeos-bootimage",
flash & boot nocturne in dev mode, verify that volume up and down
buttons work in the dev screen and that the device boots properly into
the kernel.
