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
