staging: rtl8723bs: remove some 5 GHz code

Chips that use this driver are 2.4 GHz only. Remove some code that is executed only for 5 GHz (channel > 14) . This addresses the following TODO item:

- find and remove any code for other chips that is left over

Compile tested only, due to lack of hardware.
