usb: typec: ucsi: yoga-c630: remove extra AltModes for port 1

Browse source

On Lenovo Yoga C630 the EC firmware is buggy and it cat return altmodes
for a device pushed into the port 0 (right) when the driver asks for
altmodes for port 1 (left). Since the left Type-C port doesn't support
DP anyway, ignore all UCSI_GET_ALTERNATE_MODES commands destined to the
port 1.
