dt-bindings: connector: usb: allow a single HS port

Browse Source 
Allow a single HS port to be used e.g. without reg property and a unit
address. OF graph allows a single port node, without 'reg' property.

This removes a couple of Warnings or errors on STM32MP boards.
When using single HS port currently, when doing building with W=1:
arch/arm/boot/dts/stm32mp157c-dk2.dtb: stusb1600@28: connector:
Unevaluated properties are not allowed ('port' was unexpected)
