2691cb4e42 arm64: dts: qcom: Force host mode for USB on apq8016-sbc
Commit ed75d6a969 ("arm64: dts: qcom: Collapse usb support into
one node") breaks host mode support on apq8016-sbc boards. This
is because the mux driver (tc7usb40mu) hasn't been merged.
Without that driver, we can't toggle the GPIO going to the mux to
route out the D+/D- lines to the USB hub that's on the board.

One solution would be to totally revert this change, but that
opens us up to other problems when two USB drivers are operating
the same hardware block at the same time. Let's modify the DT so
that the USB controller is always in host mode and connected to
the hub so that things like USB keyboards and mouses work. This
is the mode that most people prefer anyway with these devices. We
also delete the usb-switch node because the binding was never
accepted upstream.

In the future, we can add muxing support and then update the DT
to support both modes at runtime. Patches to support this are
already on the mailing list.

4bd40f6ceb arm64: dts: qcom: Fix MPP's function used for LED control
The qcom-spmi-mpp driver is now using string "digital" to denote
old "normal" functionality. Update DTS file.
Also update the powersource.

8883ad80c1 arm64: dts: qcom: Fix apq8016-sbc board USB related pin definitions
USB2513B HUB reset line is connected to PMIC GPIO3 not GPIO1.

Fix TC7USB40MU Dual SPDT Switch select input line control, which is
connected to PMIC GPIO4 not GPIO2 and disable the pin. It is not used
for now.

Remove user LEDs definitions, because they clash with above numbers.
