Todd Broch f5b7b32423 samus: enhance usbpd host command to return port status.
CL provides some useful information similar to the EC console command
'pd state <port>' when host command 'usbpd <port>' is sent from host
with no additional arguments.

Also added a few build asserts for role & mux strings.

BRANCH=none
BUG=chrome-os-partner:31690

  ectool --interface=lpc --dev=1 usbpd 1
  Port C1 is enabled. Role:SNK Polarity:CC1 State:6
  # has zinger attached
  ectool --interface=lpc --dev=1 usbpd 0
  Port C0 is enabled. Role:SNK Polarity:CC1 State:2
