ath79: calibrate TL-WDR4900 v2 with nvmem-cells

Browse Source 
Driver for both soc (2.4GHz Wifi) and pci (5 GHz) now pull the calibration
data from the nvmem subsystem.

This allows us to move the userspace caldata extraction for the pci-e ath9k
supported wifi into the device-tree definition of the device.

wmac's nodes are also changed over to use nvmem-cells over OpenWrt's
custom mtd-cal-data property.
