Add the basic infrastructure to periodically execute code, e.g. all
100ms. Examples for such functions might be LED blinking etc. The
functions that are hooked into this cyclic list should be small timewise
as otherwise the execution of the other code that relies on a high
frequent polling (e.g. UART rx char ready check) might be delayed too
much. This patch also adds the Kconfig option
CONFIG_CYCLIC_MAX_CPU_TIME_US, which configures the max allowed time
for such a cyclic function. If it's execution time exceeds this time,
this cyclic function will get removed from the cyclic list.

How is this cyclic functionality executed?
The following patch integrates the main function responsible for
calling all registered cyclic functions cyclic_run() into the
common WATCHDOG_RESET macro. This guarantees that cyclic_run() is
executed very often, which is necessary for the cyclic functions to
get scheduled and executed at their configured periods.

This cyclic infrastructure will be used by a board specific function on
the NIC23 MIPS Octeon board, which needs to check periodically, if a
PCIe FLR has occurred.

Now that we have consistently named symbols to enable USB host or gadget
controller support in SPL or full U-Boot, we do not need to
unconditionally build USB files nor depend on non-SPL symbols to know
when to build these common files.

This feature is not used in SPL at present. Update the Makefile to avoid
it being built.

Add a way to create and dispatch events without needing to allocate
memory. Also add a way to 'spy' on events, thus allowing 'hooks' to be
created.

Use a linker list for static events, which we can use to replace functions
like arch_cpu_init_f(). Allow an EVENT_DEBUG option which makes it
easier to see what is going on at runtime, but uses more code space.

Dynamic events allow the creation of a spy at runtime. This is not always
necessary, but can be enabled with EVENT_DYNAMIC if needed.

A 'test' event is the only option for now.

Commit 98f705c9cefd ("powerpc: remove 4xx support") removed (in 2017) the
last code that made use of bedbug debugger support. Since there aren't
any boards left that define either CONFIG_CMD_BEDBUG or a real
bedbug_init(), drop this feature from u-boot.

Rename the file lcd_simplefb.c to fdt_simplefb.c to be aligned

This converts the following to Kconfig:
   CONFIG_LCD_DT_SIMPLEFB

This patch also renames this config to CONFIG_FDT_SIMPLEFB as the code in
common/lcd_simplefb.c support CONFIG_LCD and CONFIG_VIDEO.

The last board that used to set CONFIG_LYNXKDI has been removed in
commit 242836a893ae ("powerpc: ppc4xx: remove pcs440ep support"),
doc/README.lynxkdi only talks about a MPC8260 board being supported,
and the mpc8260 support has been removed four years ago in commit
2eb48ff7a210d ("powerpc, 8260: remove support for mpc8260") already,
and common/lynxkdi.c only consists of an "#error" statement these
days, so it seems like the LYNX KDI code is dead code nowadays.
Let's remove it now.
