[PATCH v2] brcmfmac: expose firmware config files through modinfo

[matthias . bgg]

From: Matthias Brugger <mbrugger@xxxxxxxx>

Apart from a firmware binary the chip needs a config file used by the
FW. Add the config files to modinfo so that they can be read by
userspace.

Changes in v2:
In comparison to first version [0] we use wildcards to enumerate the
firmware configuration files. Wildcard support was added to dracut
recently [1].
