Subject: [PATCH v2 0/3] 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 i2c buses
- amend order of nodes.

The series is based on [1] from Johan.
