Without this patch PowerCloud CR5000 AR9382 PCIe 5GHz Wifi uses
the mac address from eeprom instead the one specified when
initializing the PCIe chip. There were two issues:
1) ap94_pci_init on the second PCIe wmac is wrong as there is only one
PCIe wmac on this device (the other wmac is the AR1022/AR9342 SoC wmac).
2) Without specifying pdata->use_eeprom there is a failure to load
firmware and caldata.
Thanks to Christian Lamparter (@chunkeey) for the heavy lifting and
help. [0]
