staging: vt6655: replace typedef struct tagSCTS_FB with struct vnt_cts_fb

Replacing members
b, wDuration_ba,  wReserved, wCTSDuration_ba_f0, wCTSDuration_ba_f1, data and
reserved2.

With
b, duration_ba, reserved, cts_duration_ba_f0, cts_duration_ba_f1, data and
reserved2

unsigned short is replaced with u16 or __le16 where necessary.

cast void pointer to pvCTS
