Bug description:
[Impact]
If you install Ubuntu onto USB storage behind a Platform 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 platform USB controller and reboot.
Booting will fail because it will be unable to find the root file system.
[Regression Risk]
Driver is only loaded when system requires ehci-platform, minimizing the
impact to all other systems.
