On some of the hardware revisions of Asus RT-AC88U, brcmfmac detects the
4366b1 wireless chip and tries to load the firmware file which doesn't
exist because it's not included in the image.
Therefore, include firmware for 4366b1 along with 4366c0. This way, all
hardware revisions of the router will be supported by having brcmfmac use
the firmware file for the wireless chip it detects.
