bcmdhd: Rework fw and nvram load

Remove original hack to set fw and nvram paths from kernel module and allow it to be defined from BoardConfig parameter without taking care of weird _b2 extension.

Its used to make a difference between chipset revisions, but since all golden devices comes with b2, it's not needed.

Also take care of dh-harald commit to fix wifi theter:
