IPQ8074 supports split firmware for q6 and m3 as well.
So add support for loading the m3 firmware before q6.
Now the drivers works fine for both split and unified
firmwares.

Right now linux-firmware ships both q6 and m3 firmware files. The driver
loads just the q6 firmware. Is it enough for the hardware to get working
WiFi?
