f77549fe74 riscv: sifive: Fix OF_BOARD boot failure
When using QEMU to have a quick test of booting U-Boot S-mode payload
directly without the needs of preparing the SPI flash or SD card images
for SiFive Unleashed board, as per the instructions [1], it currently
does not boot any more.

This was caused by the OF_PRIOR_STAGE removal, as gd->fdt_blob no longer
points to a valid DTB. OF_BOARD is supposed to replace OF_PRIOR_STAGE,
hence we need to add the OF_BOARD logic in board_fdt_blob_setup().

[1] https://qemu.readthedocs.io/en/latest/system/riscv/sifive_u.html#running-u-boot

e7fb789612 sandbox: Remove OF_HOSTFILE
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

a0cfe13715 board: sifive: Fix a potential build warning in board_fdt_blob_setup()
Commit 47d73ba4f4 ("board: sifive: overwrite board_fdt_blob_setup in u-boot proper")
added a board-specific implementation of board_fdt_blob_setup() which
takes a pointer as the return value, but it does not return anything
if CONFIG_OF_SEPARATE is not enabled. This will cause a build warning
seen when testing booting S-mode U-Boot directly from QEMU, per the
instructions in [1]:

  board/sifive/unleashed/unleashed.c: In function ‘board_fdt_blob_setup’:
  board/sifive/unleashed/unleashed.c:125:1: warning: control reaches end of non-void function [-Wreturn-type]

Return &_end as the default case.

47d73ba4f4 board: sifive: overwrite board_fdt_blob_setup in u-boot proper
Add board_fdt_blob_setup to return the device tree location which is
passed by prior stage in u-boot proper. The generic board_fdt_blob_setup
always returns _end, it mignt be ok because u-boot SPL would currently
put the dtb there, but it would be broken if we put the dtb to another
place and assigned the location into a1 register for u-boot proper. Use
the location passed by prior stage would make more sence, because we
actually pass the location to u-boot proper and want to use that one,
rather than the dtb which in _end.

We can't use CONFIG_OF_PRIOR_STAGE because it doens't distinguish the
implementation of u-boot SPL and u-boot proper, so u-boot SPL need to
reply on the prior stage to pass device tree location as well, but we
don't pass the DT from boot rom now. In addition, when
CONFIG_OF_PRIOR_STAGE is enabled, the u-boot-spl.bin and u-boot.itb won't
include the device tree.

0914011310 command: Remove the cmd_tbl_t typedef
We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.

Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.

This requires quite a few header-file additions.
