raa489000: Utilize VBUS auto discharge
The Renesas RAA489000 has an issue where GoodCRC messages are not
emitted unless the VBUS Auto Discharge Disconnect setting is enabled.
This needs to occur after determining orientation.
However, there appears to be another issue where the device will not DRP
toggle while that VBUS Auto Discharge Disconnect setting is set.
Luckily, our TCPMv2 state machine will enable/disable this setting at
these times for us. Therefore, this commit leverages the TCPCI auto
discharge disconnect function which allows DRP toggling to work.
BUG=b:149337338
BRANCH=None
TEST=Build and flash waddledoo, boot to S0, verify DUT DRP toggles.
Plug in a PD port partner, verify that PD communication works.
TEST=Repeat above test in both orientations.
