Todd Broch 6bc911d978 pd: Expand polarity logic to include Ra pull-down logic. ...

Original implemenation of polarity only addressed Rd.  This CL hopes
to address the addition of the Ra pull-down for powered accessories.

Truth table based on type-C specfication document is included in
source as well.

BRANCH=none
BUG=chrome-os-partner:28585
TEST=manual,

Setup:
  <insert hoho into samus type-C port>
  # from PD MCU console
  typec <port>

Result:
  See appropriate polarity.  For example,

  typec 1
  Port C1: CC1 445 mV  CC2 115 mV (polarity:CC1)
  Superspeed USB1

  <flip type-C accessory (hoho)>
  typec 1
  Port C1: CC1 119 mV  CC2 426 mV (polarity:CC2)
  Superspeed USB1

Also see correct polarity when just Rd is present.
