[PATCH 1/2] staging: rtl8723bs: remove cckrates{only}_included()

[Michael Straube]

In rtw_ieee80211.c there are rtw_is_cckrates_included() and
rtw_is_cckratesonly_included() which have the same functionality as
cckrates_included() and cckrates_only_included() defined in
rtw_wlan_util.c. Remove the functions from rtw_wlan_util.c and use
those from rtw_ieee80211.c. Remove the now unused variable ratelen.

[PATCH 2/2] staging: rtl8723bs: remove 5 GHz code

[Michael Straube]

Acoording to the TODO code valid only for 5 GHz should be removed.

- find and remove remaining code valid only for 5 GHz. Most of the obvious
  ones have been removed, but things like channel > 14 still exist.

Remove code path only valid for channels > 14.
