ppc: Use hard reset to recover from CC overvoltage
When sn5s330 PPC detects CC overvoltage, recover via hard reset and don't
enable PP2 sink FET directly. Also clean up the interrupt unmasking in
sn5s330_init().
BUG=b:144892533
BRANCH=grunt
TEST=Do ESD test to trigger CC1/CC2 OVP, device recovers to sink
