Add Proper Bootloader Support for Versatile Express
vexpress currently uses our master image approach which uses a fixed boot loader. However, vexpress can be configured/scripted to use different bootloaders. This would allow us to keep a fixed working bootloader, but also take the boot loader from the test iamge and instruct vexpress to boot it.
This will probably require creating a new vexpress.py device that extends master.py to deal with the new bootloader interactions.

Whiteboard
[terceiro, 2013-02-28] blocked by problem with serial line on A9 board that I was going to use for tests
[terceiro, 2013-03-27] Ryan told me during Connect that UEFI was not working on A9. We should probably ship the support for TC2 and add A9 when it is fixed
[terceiro, 2013-04-07] splitting A9 support out to a new blueprint.
Meta:
Headline: VExpress test images no longer use the master image's boot loader
Acceptance: We have a vexpress board in lava configured with this new mechanism with a tag that can accept jobs.
