Subject: [PATCH 0/5] arm64: dts: qcom: x1e80100-hp-x14: add
 usb-1-ss1-sbu-mux

The usb_1_1 port doesn't have the PS8830 repeater, but apparently some
MUX for DP altmode control. After a suggestion from sgerhold on
'#aarch64-laptops' I added gpio-sbu-mux nodes from the x1e80100-QCP
tree, and this appears to work well. It is still guesswork, but
working guesswork.

Added and rewired for usb_1_1

Also, did some more changes as tested here:

- remove unused retimer, regulators, pinctrls 
- remove unused i2c buses
- amend order of nodes
- explicitly activate smb2360 eUSB2 repeaters for the type-c connectors.
