zork: use MKBP GPIO & host event for wake on DP
GPIO-only MKBP only works when the AP is awake; we need to use
GPIO_AND_HOST_EVENT in order to support waking the AP in response to
MKBP events; in particular DP_ALT_MODE_ENTERED.
We also configure the MKBP wakeup mask so powerd can apply configuration
at runtime per chromeos-config: if no mask is configured then the
hostcmd to set the wakeup mask is not included in the firmware.
Wake on MKBP (and thus wake on DP) also requires AP firmware support.
https://review.coreboot.org/c/coreboot/+/48844 implements it for Zork.
BUG=b:174121852
TEST=Generating DP event via EC console on morphius with patched AP
firmware successfully wakes system from S3.
