brcmfmac: Prefer DT board type over DMI board type

commit a5a36720c3f650f859f5e9535dd62d06f13f4f3b upstream.

The introduction of support for Apple board types inadvertently changed
the precedence order, causing hybrid SMBIOS+DT platforms to look up the
firmware using the DMI information instead of the device tree compatible
to generate the board type. Revert back to the old behavior,
as affected platforms use firmwares named after the DT compatible.

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