rt2x00: Add missing TSF sync mode for AP operation
Currently rt2x00 uses the TSF_SYNC_BEACON mode for all beaconing interface types. However, TSF_SYNC_BEACON is meant for IBSS networks and thus implements TSF merging in the hardware. Rename TSF_SYNC_BEACON to TSF_SYNC_ADHOC to better express its purpose and introduce the missing TSF sync mode TSF_SYNC_AP_NONE which should be used for beaconing modes that don't need TSF merging.
