While all ath10k eeproms have a checksum field, so far two functions for patching ath10k MAC address have been present (and been used). This merges code to provide a single function ath10k_patch_mac in caldata.sh, having its name in accordance with ath9k functions. By doing so, correct MAC patching for current and future ath10k devices should be ensured. This patch adds checksum adjustments for several targets on ath79 and lantiq.
