[PATCH 00/13] disentangling cyclic API from schedule()

[Rasmus Villemoes]

These patches are part of a longer-term plan to properly deal with the
HW_WATCHDOG vs WATCHDOG dichotomy, and getting rid of the legacy
HW_WATCHDOG concept completely. As part of that, clean up which
headers include other headers.

While schedule(), the artist formerly known as WATCHDOG_RESET(), is
obviously called all over the tree, very few TUs make use of the
cyclic API (cyclic_register etc.). And there's really no reason at all
for global_data.h to include cyclic.h - except that some places
implicitly rely on getting their declaration of schedule() through
that include.

So this introduces a separate mostly trivial header that just serves
to declare schedule(). Then we can get rid of things that include
cyclic.h just to get that declaration.

A next, mostly mechanical step, could be to change almost all includes
of watchdog.h (which most TUs that used to have a WATCHDOG_RESET()
invocation has) to u-boot/schedule.h, because again, most of those TUs
are not really concerned with implementing init_func_watchdog_init or
need to call it. But that is for later.

CI seems happy: https://github.com/u-boot/u-boot/pull/673
