Subject: [PATCH 1/3] staging: rtl8188eu: 5 GHz channel groups removed from
 /hal/rtl8188e_hal_init.c

Unnecessary channel groups for 5 GHz removed from Hal_GetChnlGroup88E
and it transformed to pretty get_channel_group(const u8 channel).

Also removed code for 5 GHz frequency in Hal_ReadPowerValueFromPROM_8188E.
