Add ZL_REF_SYNC_CTRL_MODE_REFSYNC_PAIR and ZL_REF_SYNC_CTRL_PAIR register definitions. Add inline helpers to get and set the sync control mode and sync pair fields of the reference sync control register: zl3073x_ref_sync_mode_get/set() - ZL_REF_SYNC_CTRL_MODE field zl3073x_ref_sync_pair_get/set() - ZL_REF_SYNC_CTRL_PAIR field Add inline helpers to get and set the clock type field of the output mode register: zl3073x_out_clock_type_get/set() - ZL_OUTPUT_MODE_CLOCK_TYPE field Convert existing esync callbacks to use the new helpers.
