[PATCH] V4L: 917: fixes some bugs in msp3400

- Adds missing msp34xxg_reset to VIDIOC_S_STD (just like VIDIOCSCHAN).
- Improves msp3400 debug messages.
  Now, all kernel message in msp3400.c use the same prefix
  and include the I2C bus to differentiate between multiple
  msp3400 I2C chips.
- Correctly prints the chip identifier for the msp44xx chips.
- msp34xxg cleanups.
