ath79: calibrate TP-LINK TL-WR2543ND with nvmem

Browse Source 
Driver for and pci wlan card 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.

The wifi mac address remains correct after these changes, because When both
"mac-address" and "calibration" are defined, the effective mac address
comes from the cell corresponding to "mac-address" and
mac-address-increment.

Test passed on my tplink tl-wr2543nd.
