With "getting WIFI MAC from NVMEM" working on ath79 on 5.10,
the next logical step I think is to utilize nvmem subsystem
to also get the calibration data from there.
This will tremendously speed up the wifi bring-up, since
we no longer need the userspace helper for the simple
devices that can just load them from there.
included with this patch is a package/mac80211/refresh.
Tested on: WNDR3700v2, TP-Link Archer C7v2
