sandbox: Add a build for VPL

Browse source 
Add an initial VPL build for sandbox. This includes the flow:

   TPL (with of-platdata) -> VPL -> SPL -> U-Boot

To run it:

   ./tpl/u-boot-tpl -D

The -D is needed to get the default device tree, which includes the serial
console info.

Add a Makefile check for OF_HOSTFILE which is the option that enables
devicetree control on sandbox.

VPL (Verifying Program Loader)
------------------------------
Sandbox provides an example build of vpl called `sandbox_vpl`. This can be run
using::
/path/to/sandbox_vpl/tpl/u-boot-tpl -D
It starts up TPL (first-stage init), then VPL, then runs SPL and finally U-Boot
proper, following the normal flow for a verified boot. At present, no
verification is actually implemented.
Debugging the init sequence
