qcacld-3.0: Remove config item OkcEnabled remnants

Change Ib2fcdc6318adb488eca5cf47b2b59541020e6009 ("qcacld-3.0: Add
support for PMKID modes of PMK caching and OKC") replaced the config
item OkcEnabled with a new item pmkidModes. However it left behind the
documentation as well as the CFG macros for OkcEnabled, so now remove
those remnants, along with the prototype for the now removed function
hdd_is_okc_mode_enabled().
