4f5c48d5fd imx8m: set sane default value for SPL_LOAD_FIT_ADDRESS
I enabled IMX_HAB on an imx8mp board, but even though I knew about the
implementation, I forgot that I had to provide a sane value for
SPL_LOAD_FIT_ADDRESS. The help text for IMX_HAB doesn't mention this
implicit requirement, and there's no build-time warning; the default
0x0 value just ends up being returned from
board_spl_fit_buffer_addr(), obviously resulting in a non-booting
board.

The existing imx8m* board configs that set a non-zero value currently
all use 0x44000000. The actual value doesn't matter too much, but 0 is
always wrong for imx8m platforms. So just use 0x44000000 as default
for those platforms.

4457e5c61d cyclic: introduce u-boot/schedule.h
I noticed an "unnecessary" include of <cyclic.h> in
global_data.h, in the sense that nothing in cyclic.h is needed in
order to define 'struct global_data'.

Well, it's not unnecessary, as it implicitly ensures that everybody
gets a declaration of schedule(), and schedule() is (obviously) called
all over the tree. Almost none of those places directly include
<cyclic.h>, but for historical reasons, many do include
<watchdog.h> (most schedule() instances are replacements of
WATCHDOG_RESET()).

However, very few TUs actually need the declarations of the
cyclic_register() and struct cyclic_info, and they also don't really
need anything from the watchdog.h header.

So introduce a new header which just contains a declaration of
schedule(), which can then be included from all the places that do
call schedule(). I removed the direct reference to cyclic_run(),
because we shouldn't have two public functions for doing roughly the
same without being very explicit about when one should call one or the
other.

Testing of later patches that explicitly include <schedule.h> when
schedule() is used revealed a problem with host tool build on win32,
which apparently picked up a host <schedule.h>. To avoid that problem,
put the new header in include/u-boot/ and hence make the include
statements say <u-boot/schedule.h>.

7f3d53c8bf watchdog: gpio_wdt: add support for stoppable devices
Back when I added this driver in commit 2ac8490412c9, I wrote

    The corresponding linux driver apparently has support for some
    watchdog circuits which can be disabled by tri-stating the gpio, but I
    have never actually encountered such a chip in the wild;

That has changed now; I have a board with just such a watchdog on my
desk currently. Add support for that.

- For a hw_algo="toggle" device, the gpio is requested as output if the
  always-running flag is set, otherwise as input.

- The ->start() method is updated to change the direction to output when
  required (i.e. it is not always-running).

- The ->stop() method is implemented, but of course reports failure if
  always-running.

As I still haven't met any hw_algo="level" devices, I'm not entirely
sure how they fit in, but I'm borrowing logic from the corresponding
linux driver:

- In ->probe(), such devices always request the gpio as GPIOD_IS_OUT.

- In ->stop(), the linux driver has an "eternal ping" comment and sets
  the gpio to (logic) high.

Stefan:
Added necessary changes in test/dm/wdt.c to fix CI build breakage, as
suggested by Rasmus.
