mwifiex: common set_wiphy_params cfg80211 handler for AP and STA interface
Add support for setting fragmentation threshold, RTS threshold
and retry limit.
Since wiphy parameters are properties of physical device,
appropriate function to set phy parameters is invoked depending
upon bss_type(STA or AP) for each virtual interface.
