arm64: dts: qcom: sc7180-trogdor: Add nodes for onboard USB hub

Browse Source 
Add nodes for the onboard USB hub on trogdor devices. Remove the
'always-on' property from the hub regulator, since the regulator
is now managed by the onboard_usb_hub driver.

For anyone using trogdor-based devices on Linux, it should be
noted that this requires "CONFIG_USB_ONBOARD_HUB=y".
