staging: vt6655: replace typedef struct tagSRTS_a_FB with struct vnt_rts_a_fb 

Replacing members
a, wDuration, wReserved, wRTSDuration_f0, wRTSDuration_f1 and data
with
a, duration, reserved, rts_duration_f0, rts_duration_f1 and data

unsigned short is replaced with u16 or __le16 where necessary.

cast void pointer to pvRTS

Creating the new structure in rxtx.h
