[v1] arm64: dts: ti: verdin-am62: add support for Verdin USB1 interface
Commit Message
From: Andrejs Cainikovs <andrejs.cainikovs@toradex.com>
Add support for Verdin USB1 interface, implements role switch
functionality using "gpio-usb-b-connector", VBUS is also now
controlled with "regulator-fixed" using a standard GPIO.

this should be "SODIMM_155"
