OF_HOSTFILE is used on sandbox configs only. Although it's pretty
unique and not causing any confusions, we are better of having simpler
config options for the DTB.
So let's replace that with the existing OF_BOARD. U-Boot would then
have only three config options for the DTB origin.
- OF_SEPARATE, build separately from U-Boot
- OF_BOARD, board specific way of providing the DTB
- OF_EMBED embedded in the u-boot binary(should not be used in production

Changes since v1:
- Added internal error value on board_fdt_blob_setup(). Arguably
we can just check against NULL and simplify this even more if we
don't care about the errno
- OF_BOARD is now default for sandbox builds
