[PATCH] drivers/staging/rtl8188eu remove 5GHZ specific code

My first patch.
This based from linux-next tree.
Removes code valid only for 5 HGz, as per the TODO, and also some formating issues.
If this device is only supported for sub 5GHZ hardware than this
change should not harm its intended audience. The caller 
of Hal_GetChnlGroup88E() does not check for false.

That is up in the subject line, no need to put it in the body.

No need for that in the changelog :)

Nor that :)

But this line isn't formatted properly :(

Were you able to test this?
