Subject: [PATCH] brcmfmac: of: Use board compatible string for board type

When "brcm,board-type" is not explicitly set in devicetree
fallback to board compatible string for board type.

Some of the existing devices rely on the most compatible device
string to find best firmware files, including Raspberry PI's[1].

Fixes: 7682de8b3351 ("wifi: brcmfmac: of: Fetch Apple properties")
