OF_HOSTFILE is used on sandbox configs only.  Although it's pretty
unique not a source of any confusions,  we are better of having simple
config options for the DTB.
So let's replace that with the existing OF_BOARD.  This will make U-Boot
have only three different 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, but discouraged from being used
  in production
