The hndpmu source file has functions for brcmfmac and brcmsmac driver
but it turns out that on function level there is no reuse so for
the brcmsmac its set of functions now reside in wlc_pmu.c.

Code cleanup. Functions wlc_edcf_setparams() and
wlc_wme_setparams() duplicate code amongst each other. This commit
attempts to make life easier for the reviewer, by introducing non
functional changes that bring wlc_edcf_setparams() more in line
with wlc_wme_setparams(). As a result the subsequent commit can be
reviewed more easily.
