ARM: dts: msm: Default none mode for primary USB controller on SA8195

Keep primary USB controllers in none mode by default on
target bootup. This is required to pass freeze callback when
target resumes from hibernation and bare kernel is booting.
We will keep the controller in peripheral mode via userspace
for full boot chain.
