honeybuns: fix CC voltage thresholds
honeybuns: fix CC voltage thresholds

The Rp resistor on CC1 is set for a 3.0A capability,
so Vnc (no-connection voltage) is 2.45 V.

CC2 is not connected (captive cable), so for a PD source, it's identical
to being always pulled-up to 3.3V (no sink connection).
