usb: typec: ucsi: fix UCSI on SM8550 & SM8650 Qualcomm devices

On SM8550 and SM8650 Qualcomm platforms a call to UCSI_GET_PDOS for
non-PD partners will cause a firmware crash with no
easy way to recover from it.

Add UCSI_NO_PARTNER_PDOS quirk for those platform until we find
a way to properly handle the crash.
