Todd Broch 7698c323ea samus: Add host command to query USB type-C accessory attached. ...

PD accessories that are RW update-able will broadcast their rw_hash
SHA1 digest upon connection to the PD MCU which will store it.

For update purposes, the host needs that accessories device id and
rw_hash to determine its proper firmware update payload.

This CL creates a host command that requests the type-C accessory info
attached to a particular port.  It also implements an ectool command
to expose the host command.

BRANCH=none
BUG=chrome-os-partner:31361
TEST=manual,
  # connect zinger to port 1 on samus
  ectool --dev=1 --interface=lpc infopddev 1
  Port:0 Device:1 Hash:  0x7f4d7a13 0xf07b65b9 0x41181e10 0xb99b3d5f 0x9dee1206

  ectool --dev=1 --interface=lpc infopddev 0
  Port:0 has no valid device

Also do the same on port 0 with similar results.
