Only mt7615 uses v1 version. Also, some of released firmware doesn't
have hdr->fw_ver.

so there are some v2 fw version w/o fw_ver field, correct? Is this fw in
linux-firmware?

I will post it.

Actually all MTK stock firmwares don't include that version info, so
considering users may use binaries from some manufactures. I think this
can make life more easier. This patch should work for all firmwares we
can find everywhere. Even 7615 v2 can be backward compatible to v1.
