V4L/DVB (11934): Change order for FM tune 



Change order data of buffer in FM simple_tune function. It is usefull for:

1. Set data of tuner with CP bit UP. 0xCE for MK5 or 0xC6 for MK3
2. When call simple_fm_tune, read this byte from config and overwrite
this byte in function simple_radio_bandswitch for set CP bit to OFF.

Of course it can be usefull for other tuner for overwrite default
settings of FM.
