staging: brcm80211: make use of fls bit operation in wlc_phy_compute_dB
wlc_phy_compute_dB converts absolute power value to dB implementing
a fixed point calculation for 10*log10(x). It does this by determining
the most significant bit for value x. This can be done using the fls()
bit operation, which has arch specific and possibly more efficient
implementation.
