Alec Berg 58719e3073 pd: use pdcmd task to handle tcpc interrupt 
Use the PDCMD task to handle PD MCU interrupts, and use it
to trigger the tcpc_alert().

Note this fixes bug on Glados and Oak that could cause watchdog
reset because tcpc_alert() which uses i2c to talk to tcpc was
called from hooks task and can delay tickling watchdog.

BUG=chrome-os-partner:40920
BRANCH=none
TEST=load on glados and plug zinger into both ports many times.
make sure we get a stable contract and no watchdog reset.
