History
Todd Broch a3913d99d7 pd: dingdong/hoho: HPD over USB PD. 
HPD needs to be transported of USB PD as both SBU lines are consumed
for differential AUX signalling.

This CL does the following:
1. Enables GPIO DP_HPD as interrupt
2. Sends debounced HPD across CC via the SVDM DP status message

BRANCH=none
BUG=chrome-os-partner:31192,chrome-os-partner:31193
TEST=manual,

From servo w/ GPIO attached to HPD drove the following transactions
after inserting with HPD low initially:

    # e1: hpd_high
    # e2: hpd_low
    # non-registered glitch
    # e3: hpd_high followed by hpd_low
    # e4: hpd high
    # non-registered glitch
    # e5: hpd_irq
    # e6: hpd_irq
    # e7: hpd_irq
    # e8: hpd_low followed by hpd_high
