[0/3] arm64: dts: qcom: make dev boards prefer usb host mode

Many of the Qualcomm development boards feature DRD capable
type-c ports. However these boards differ from smartphones in their
usage, and it's generally preferred that they would enter host mode by
default when given the choice.

This doesn't affect connection to a host-only PC, since the controller
is still DRD capable.

The RB1/2 are a special case, since they feature an on-board USB hub and
a manual dip switch to toggle between it and the type-c port. Preferring
host mode offers a useful hint to the software if it doesn't feature a
fully DRD capable USB controller driver, it can just use the default
mode (rather than defaulting to peripheral mode unconditionally).
