[PATCH v2 3/3] arm64: dts: qcom: kaanapali: Mark the USB controller as a Type-C mode switch

[Joonhoe Kim <26rote@gmail.com>]

When the USB3-DP combo PHY is a mode switch, DisplayPort pin
assignments C and E put it in DP-only mode, where it stops the USB3
PIPE clock. Make the USB controller a mode switch as well, so that it
moves to the UTMI clock first and keeps its USB 2.0 port working.
