usb: typec: change altmode SVID to u16 entry

Browse Source 
As stated in the changelog for the commit 7b458a4c5d73 ("usb: typec: Add
typec_port_register_altmodes()"), the code should be adjusted according
to the AltMode bindings. As the SVID is 16 bits wide (according to the
USB PD Spec), use fwnode_property_read_u16() to read it.
