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.

Changes in v8: - Update defconfig to account for option changes - Drop reference to old OF_HOSTFILE option
Changes in v7: - Rebase to master - Update some options based on settings in master
Changes in v6: - Add docs for sandbox_vpl build - Drop TPL_HASH_SUPPORT patch since we only have SPL_HASH now
Changes in v4: - Add a sandbox_vpl build - Update cover letter
