board: sl28: disable recovery watchdog

Browse source 
This board has an internal watchdog which supervises the board startup.
Although, the initial state of the watchdog is configurable, it is
enabled by default. In board_late_init(), which means almost everything
worked as expected, disable the watchdog.

Install the bootloader on the board
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Please note, this bootloader doesn't support the builtin watchdog (yet),
therefore you have to disable it, see below. Otherwise you'll end up in
the failsafe bootloader on every reset::
To install the bootloader binary use the following command::
> tftp path/to/u-boot.rom
> sf probe 0
> sf update $fileaddr 0x210000 $filesize
The board is fully failsafe, you can't break anything. But because you've
disabled the builtin watchdog you might have to manually enter failsafe
mode by asserting the ``FORCE_RECOV#`` line during board reset.
The board is fully failsafe, you can't break anything. If builtin watchdog
is enabled, you'll automatically end up in the failsafe bootloader if
something goes wrong. If the watchdog is disabled, you have to manually
enter failsafe mode by asserting the ``FORCE_RECOV#`` line during board
reset.
