usb: typec: ucsi: Remove incorrect warning

Browse Source 
commit 415ba26cb7 upstream.

Sink only devices do not have any source capabilities, so
the driver should not warn about that. Also DRP (Dual Role
Power) capable devices, such as USB Type-C docking stations,
do not return any source capabilities unless they are
plugged to a power supply themselves.
