staging: vt6656: device.h Remove typedef enum __device_init_type.

Since typedef enum __device_init_type is only ever called
in one state.

Remove the typedef from main_usb.c:device_init_registers and
replace with macro values. The other values may be needed later.

Apply cold value to sInitCmd.byInitClass.

Remove if braces and correct formatting within.
