kernel: add ath10k support for of_get_mac_address
ath10k doesn't currently support the standard function to get mac-address from the dts. Add this for both ath10k and ath10k-ct Signed-off-by: Ansuel Smith <ansuelsmth@gmail.com>

+Subject: [PATCH 1/2] ath10k: Try to get mac-address from dts
+
+Most of embedded device that have the ath10k wifi integrated store the
+mac-address in nvmem partitions. Try to fetch the mac-address using the
+standard 'of_get_mac_address' than in all the check also try to fetch the
+address using the nvmem api searching for a defined 'mac-address' cell.
+Mac-address defined in the dts have priority than any other address found.
+
+Tested-on: QCA9984 hw1.0 PCI 10.4
