7fe32b3442 event: Convert arch_cpu_init_dm() to use events
Instead of a special function, send an event after driver model is inited
and adjust the boards which use this function.

42fdcebf85 event: Convert misc_init_f() to use events
This hook can be implmented using events, for the three boards that
actually use it.

Add the event type and event handlers. Drop CONFIG_MISC_INIT_F since we
can just use CONFIG_EVENT to control this. Since sandbox always enables
CONFIG_EVENT, we can drop the defconfig lines there too.

5b896ed585 event: Add events for device probe/remove
Generate events when devices are probed or removed, allowing hooks
to be added for these situations.

This is controlled by the DM_EVENT config option.

87a5d1b5d0 event: Add basic support for events
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.
