The original driver has some code that supports many different chips; however, 
the present one only works for RTL8188E.

In the current driver, ODM_RTL8188E is always the only bit in odm_ic_type, thus 
it is always 16. As a result (_ic_type & ODM_IC_11N_SERIES) is always equal to 
_ic_type, which is why I simplified the macro.

If you really prefer the original version of the macro, I will leave it.
