[PATCH v2 4/6] brcmfmac: Set board_type used for nvram file selection to machine-compatible

[Hans de Goede]

For of/devicetree using machines, set the board_type used for nvram file
selection to the first string listed in the top-level's node compatible
string, aka the machine-compatible as used by of_machine_is_compatible().

The board_type setting is used to load the board-specific nvram file with
a board-specific name so that we can ship files for each supported board
in linux-firmware.
