Its necessary to establish an initial state on the wake-detect lines before enabling timesync on APB/GPB in order to ensure all GPIO edge-transitions are correctly interpreted by the receiving processor. This patch adds the operations defined in the Greybus specification to greybus_protocols.h, this involves adding the SVC_TIMESYNC_WAKE_PINS_ACQUIRE and SVC_TIMESYNC_WAKE_PINS_RELEASE commands and moving the 'strobe_mask' parameter from 'struct gb_svc_timesync_enable_request' to 'struct gb_svc_timesync_wd_pins_acquire_request' since the communication of the strobe_mask will be communicated before preparing any of the bridges to receive the TimeSync pulses. A separate patch to the greybus specification describes the transition between the wake sub-state and the timesync sub-state.
