6092ce50ef event: add new EVT_SETTINGS_R event
Introduce EVT_SETTINGS_R, triggered post-relocation and before console
init.

This event gives an option to perform any platform-dependent setup,
which needs to take place before show_board_info(). Usage examples
include readout of EEPROM stored settings.

b53ab97150 event.h: Documented some newly added portions better
After the merge of v2023.10-rc4 to next include/event.h needs to be
fully documented in order for documentation builds to complete.  Rewords
two of the event_t descriptions to be docbook style and better match the
rest of this enum.  Fix two typos (flag->flags) in other comments.

91caa3bb89 event: Use an event to replace last_stage_init()
Add a new event which handles this function. Convert existing use of
the function to use the new event instead.

Make sure that EVENT is enabled by affected boards, by selecting it from
the LAST_STAGE_INIT option. For x86, enable it by default since all boards
need it.

For controlcenterdc, inline the get_tpm() function and make sure the event
is not built in SPL.

13a7db9ab1 x86: Convert arch_fsp_init() to use events
Convert this to use events instead of calling a function directly in the
init sequence.

Rename it to arch_fsp_init_f() to distinguish it from the one that happens
after relocation.

For FSPv2 nothing needs to be done here, so drop the empty function.

ba5e3e1ed0 event: Support a simple spy record
The current event spy is always passed the event context and the event.
The context is always NULL for a static spy. The event is not often used.

Introduce a 'simple' spy which takes no arguments. This allows us to drop
the adaptation code that many of these spy records use.

Update the event script to find these in the image.

98887ab802 event: Add an event for device tree fixups
At present there is a confusing array of functions that handle the
device tree fix-ups needed for booting an OS. We should be able to switch
to using events to clean this up.

As a first step, create a new event type and call it from the standard
place.

Note that this event uses the ofnode interface only, since this can
support live tree which is more efficient when making lots of updates.

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.
