[PATCH v5 2/6] Bluetooth: btqca: Add IPQ5018 support

[George Moussalem via B4 Relay <devnull+george.moussalem.outlook.com@kernel.org>]

From: George Moussalem <george.moussalem@outlook.com>

Add the IPQ5018 SoC type and support for loading its firmware.

The firmware tested has been taken from GPL sources of various router
boards. Firmware files needed are:
- qca/bt_fw_patch.mbn
- qca/mpnv10.bin
