ath79: calibrate TP-LINK TL-WR2543ND with nvmem
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. Signed-off-by: Edward Chow <equu@openmail.cc>
