ppc/syv682x: support C version
C version won't block I2C accessing to CONTROL4(to on/off Vconn) reg
when smart discahrge enabled. This allows us to re-enable the smart
discahrge on boards using SYV682C. This CL support the feature by
adding:
1. CONFIG_USBC_PPC_SYV682C
2. CONFIG_USBC_PPC_SYV682X_SMART_DISCHARGE
also, hayato uses different SYV682 versions across revisions, add a
overridable function syv682x_board_is_syv682c() for handling
board revision issue.
BUG=b:160548079 b:176876036
TEST=Hayato meets tVconnOff, and tVbusDischarge
BRANCH=asurada
