mb/intel/tglrvp: Enable EC sync interrupt

TGLRVP U/Y has GPP_A15 assigned to EC_HPD as EC_SYNC_IRQ. Configure this
GPP_A15 gpio as active low and level interruptible. Enable EC sync
interrupt configuration.

BUG=None
TEST=Booted to kernel and verified EC_SYNC_IRQ in the scope of CREC
current resource settings.
