mb/google/nocturne: Define GPP_D17 as EC_SYNC_IRQ
Use GPIO GPP_D17 pin as the EC sync interrupt and provide this value
to the embedded controller to be exported to the OS.
This interface was tested on a reworked Nocturne board with modified
EC and a modified kernel driver to ensure that the interrupt asserts
as expected and can be used by the kernel driver.
