Support root on ehci-msm attached storage

[dann frazier]

[Impact]
If you install Ubuntu onto USB storage behind a Qualcomm QSD/MSM USB host controller, it will not be able to boot because the generated initramfs will not include the host controller driver.

[Test Case]
Install to a USB stick attached to QSD/MSM controller and reboot. Booting will fail because it will be unable to find the root file system.

[Regression Risk]
This driver is only available on ARM platforms, minimizing the impact to all other architectures.

Marking linux as affected, since we also need qhci-msm module included in the usb-modules udeb.
