b43: use the bitrev helpers rather than rolling a private one

Browse source

The 4-bit reversal flip_4bit is replaced with the bitrev helper
bitrev8 and a 4-bit shift.  The B43_WARN is moved to the location
where a register is read from for checking there.  The other caller
explicitly passes an array index which is guaranteed to be within range
and so a B43_WARN is not added there.
