At present the initcall list consists of a list of function pointers. Over
time the initcall lists will likely change to mostly emitting events,
since most of the calls are board- or arch-specific.
As a first step, allow an initcall to be an event type instead of a
function pointer. Add the required macro and update initcall_run_list() to
emit an event in that case, or ignore it if events are not enabled.
The bottom 8 bits of the function pointer are used to hold the event type,
with the rest being all ones. This should avoid any collision, since
initcalls should not be above 0xffffff00 in memory.
Convert misc_init_f over to use this mechanism.
Add comments to the initcall header file while we are here. Also fix up
the trace test to handle the change.

When running the trace test on the sandbox platform, the current size
of 16MiB is no longer large enough for capturing the entire trace
history, and results in truncation. Use a size of 32MiB for the trace
buffer on the sandbox platform while running the trace test.

We expect the profile and bootstage to agree on timing, but when
running on slow machines there can be a larger descrepency. Increase the
tolerance to fix this.

Add a test which runs sandbox, collects a trace and makes sure it can
be processed by trace-cmd. This should ensure that this feature continues
to work as U-Boot and trace-cmd evolve.
