nwztools/scsitool: fix devinfo, add dhp
The devinfo request returned the raw data, now the tool prints the various fields. Also add support for the dhp (destination/headphones/color ...): this one is untested because it's only supported starting from A10 or A20. There is still a problem with the dpcc prop: although it should work for DEVINFO, it does not, despite the fact that the get_dev_info command works and is internally (on the Sony) translated into a dpcc request. I keep the code just in case. Change-Id: I5aa8ef4afb0b11d3c0ddfa3d38f3e737ee1aff66
