ath10k: add qca6164 support
This adds additional 0x0041 PCI Device ID definition to ath10k for QCA6164 which is a 1 spatial stream sibling of the QCA6174 (which is 2 spatial stream chip). The QCA6164 needs a dedicated board.bin file which is different than the one used for QCA6174. If the board.bin is wrong the device will crash early while trying to boot firmware. The register dump will look like this: ath10k_pci 0000:02:00.0: firmware register dump: ath10k_pci 0000:02:00.0: [00]: 0x05010000 0x000015B3 0x000A012D 0x00955B31 ... Note the value 0x000A012D. Special credit goes to Alan Liu <alanliu@qca.qualcomm.com> for providing support help which enabled me to come up with this patch.
