This series is a component of a series which enables full Type-C port
manager support on pm8150b hardware as found on sm8150 and sm8250.

When we change the orientation of the Type-C cable, we must also change the
lane allocation in the qmp phy to match the reported orientation.
The first patch is a simple typo fix in the original upstream commit.
The second patch implements a reasonably complex dance to reset the qmp phy
for the orientation switch. This necessitates registering for the Type-C
switch, resetting the PHY and then bringing the PHY back up with the correct
orientation.
The second patch is based on Wesley's original submission, reworked by
Dmitry and with a few fixes applied by me.
