[PATCH 3/3] arm64: dts: qcom: eliza-mtp: Enable USB and ADSP support

[Abel Vesa]

The Eliza MTP features a single USB Type-C port. Its USB 2.0 lines are
routed through an eUSB2 repeater provided by the PM7750BA PMIC.

Describe the port and repeater, and enable the USB controller and PHYs.

Also specify the ADSP firmware and enable the remoteproc.

That's the default if dr_mode is absent, drop

Shouldn't this be l7k? Looking at kera-usb.dtsi I see the vdd-supply for
eusb2_phy0 as l7k. I don't see this being overriden by anything else
downstream either.

Just bringing it up since I copied this part for another Eliza platform
(USB 2 only) and USB failed until I fixed this supply.

Looking at some diagrams, L7K seems to be the right one indeed
