Christian Lamparter 10ad6d6e07 ipq40xx: integrate ath10kcal_patch_mac into ath10kcal_patch_mac_crc
In the thread: "ipq806x: add ath10k calibration data MAC addresses patching"
Chuanhong Guo <gch981213@gmail.com> noted that:
"All ath10k calibration data have a checksum at 0x2.
ath10kcal_patch_mac works for QCA9880/QCA9882 only because
the ath10k firmware for these two chips doesn't check the
checksum value. (QCA proprietary driver checks this and
refuses to use caldata with incorrect checksum.)"

This patch updates 11-ath10k-caldata of the ipq40xx target accordingly.
