Firmware revisions providing sta keepalive service
have it enabled by default.

mac80211 already does idle connection polling so
it makes no sense to duplicate this in ath10k.
mac80211 wouldn't even know of the offloaded
keepalive NullFunc frames.

Introduce a new wmi interface controls noise floor (NF) calibration

It allows users to modify frequency of NF calibration in millisecond

so that RSSI reported in receive frames is more realistic.

echo trigger > /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_scan_ctl

echo disable > /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_scan_ctl
cat /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_scan0 > samples

rename a few functions to make more sense while at
