staging: vt6656: refactor power save operation
At present the power save wake uses the listening interval and
the slow path to wake up.
The following using a beacon interval of 100 and
listen interval of 5.
The TBTT set at 100 wake-up sequence;
100 TBTT wake-up set to listen interval.
200 TBTT
300 TBTT
400 TBTT --> call vnt_next_tbtt_wakeup on slow path
Beacon heard and passed through at the approx 500 interval.
500 TBTT
600 TBTT wake-up set to listen interval
The TBTT set at 500 wake-up sequence and always listen flagged on;
100 No TBTT
200 No TBTT
300 No TBTT
400 No TBTT
500 TBTT - beacon heard and passed through
600 No TBTT
A further enhancement because the TBTT is more precise
the dtim_period can be used instead.
When Power save is off the TBTT continues to run at the listen
interval but all the other beacons are passed.
The code in vnt_int_process_data is no longer required.
