usb: typec: ucsi: fix UCSI on buggy Qualcomm devices
On sevral Qualcomm platforms (SC8180X, SM8350, SC8280XP) a call to
UCSI_GET_PDOS for non-PD partners will cause a firmware crash with no
easy way to recover from it. Since we have no easy way to determine
whether the partner really has PD support, shortcut UCSI_GET_PDOS on
such platforms. This allows us to enable UCSI support on such devices.
