arm64: dts: qcom: msm8916-ufi: make UDC dual mode

It's possible to use this device with a (non-standard) hub to get USB
working in host mode, but dr_mode="peripheral" prevents the UDC to
do so.
Remove dr_mode="peripheral" and add usb-role-switch so that it defaults
to otg mode and can be switched to host mode in userspace.
