[media] em28xx-v4l: fix device initialization in em28xx_v4l2_open() for radio and VBI mode 

- bail out on unsupported VFL_TYPE
- em28xx_set_mode() needs to be called for VBI and radio mode, too
- em28xx_wake_i2c() needs to be called for VBI and radio mode, too
- em28xx_resolution_set() also needs to be called for VBI
