drivers/sbus/: cleanups

This patch contains the following cleanups:
- make the following needlessly global code static:
  - char/uctrl.c: uctrl_get_event_status()
  - char/uctrl.c: uctrl_get_external_status()
  - char/vfc_dev.c: struct vfc_dev_lst
  - char/vfc_dev.c: vfc_lock_device()
  - char/vfc_dev.c: vfc_unlock_device()
  - char/vfc_dev.c: vfc_captstat_reset()
  - char/vfc_dev.c: vfc_memptr_reset()
  - char/vfc_dev.c: vfc_csr_init()
  - char/vfc_dev.c: vfc_saa9051_init()
  - char/vfc_dev.c: init_vfc_hw()
  - char/vfc_dev.c: init_vfc_devstruct()
  - char/vfc_dev.c: init_vfc_device()
  - char/vfc_dev.c: vfc_get_dev_ptr()
  - char/vfc_dev.c: vfc_capture_start()
  - char/vfc_dev.c: vfc_capture_poll()
  - char/vfc_dev.c: vfc_port_change_ioctl()
  - char/vfc_dev.c: vfc_set_video_ioctl()
  - char/vfc_dev.c: vfc_get_video_ioctl()
  - char/vfc_i2c.c: vfc_i2c_wait_for_bus()
  - char/vfc_i2c.c: vfc_i2c_wait_for_pin()
  - char/vfc_i2c.c: vfc_i2c_xmit_addr()
  - char/vfc_i2c.c: vfc_i2c_xmit_byte()
  - char/vfc_i2c.c: vfc_i2c_recv_byte()
  - dvma.c: init_one_dvma()
- remove an unused variable from a function:
  - char/uctrl.c: ts102_uctrl_init()
- remove the following unused and empty function:
  - char/uctrl.c: uctrl_set_video()
