The brcm43430 chip needs different firmware files for chip revision 0
and 1. The file currently in linux-firmware is for revision 1 only.

This commit makes brcmfmac request brcmfmac43430a0-sdio.bin instead
of brcmfmac43430-sdio.bin for revision 0 chips.

Note that the behavior for revision 1 chips is not changed, ideally those
would load brcmfmac43430a1-sdio.bin, but that will break existing setups.

Unfortunately, there is no "brcmfmac43430a0-sdio.bin" in linux-
firmware. Therefore, my custom board fails:

# [   24.894241] brcmfmac mmc0:0001:1: Direct firmware load for
brcm/brcmfmac43430a0-sdio.bin failed with error -2

[   26.934186] brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000):

Can someone provide the firmware file, please?

I've put all the versions I've been able to find here:

Note that the 7.x.y.z version does not seem to have any useful meaning,
higher is not necessarily newer :|

So date wise brcmfmac43430a0-sdio.bin.7.10.1.244.ucode940.1020 is the newest
and IIRC that one works well for me.

ucode version wise, brcmfmac43430a0-sdio.bin.7.10.68.5.ucode997.0 is newer,
but the .0 in 997.0 makes it feel like an unproven release to me.
