[PATCH] soc: qcom: pmic_glink: enable UCSI on sc8280xp

[Johan Hovold]

Commit ad3dd9592b2a ("soc: qcom: pmic_glink: disable UCSI on sc8280xp")
disabled UCSI shortly after it had been enabled to fix a regression that
was observed on the Lenovo ThinkPad X13s.

Specifically, disconnecting an external display would trigger a system
error and hypervisor reset but no one cared enough to track down the bug
at the time.

The same issue was recently observed on X Elite machines, and commit
f47eba045e6c ("usb: typec: ucsi: Set orientation as none when connector
is unplugged") worked around the underlying issue by setting the
connector orientation to 'none' on disconnect events to avoid having the
PHY driver crash the machine in one orientation.

Enable UCSI support also on sc8280xp now that the DisplayPort disconnect
crashes are gone.
