[PATCH v2 2/2] platform/chrome: cros_ec_typec: Reorder altmode registration

[Andrei Kuchynski]

By default, alternate mode priorities are set in registration order, with
the last mode registered taking precedence. Changing the registration order
of alternate modes prioritizes DisplayPort over Thunderbolt.
