Description

Fix enum warnings in ath_hal's ar9300

This fixes a number of clang 19 warnings:

The FBIN2FREQ() and FREQ2FBIN() macros in ar9300eep.h are invoked
in most places around the ath_hal code with a (effectively) boolean
second argument, corresponding to "is this 2GHz?". But in the code that
is warned about, the value HAL_FREQ_BAND_2GHZ is of a different
non-boolean type, HAL_FREQ_BAND.

Update the FBIN2FREQ() and FREQ2FBIN() macros to interpret the
second argument as boolean value, and rename the macro parameter names
to better describe their meaning.
