wil6210: NOC time-out fixes 



On MSM there is NOC time-out in case the 11AD device wake-up
latency exceeds 6.7ms.
In order to guarantee fast wake-up in 11AD BL, set USAGE_8
bit 0, which prevents deep sleep in BL.
In addition, to shorten the wake-up time in operational FW,
mark the FW to set T_POWER_ON to 0, by setting BIT 1 of USAGE_8
register.
