According to the POSIX standard, %p is supposed to print a pointer "as
if by %#x", meaning the "0x" prefix should automatically be prepended.
All other implementations out there (glibc, Linux, even libpayload) do
this, so we should make coreboot match. This patch changes vtxprintf()
accordingly and removes any explicit instances of "0x%p" from existing
format strings.
How to handle zero padding is less clear: the official POSIX definition
above technically says there should be no automatic zero padding, but in
practice most other implementations seem to do it and I assume most
programmers would prefer it. The way chosen here is to always zero-pad
to 32 bits, even on a 64-bit system. The rationale for this is that even
on 64-bit systems, coreboot always avoids using any memory above 4GB for
itself, so in practice all pointers should fit in that range and padding
everything to 64 bits would just hurt readability. Padding it this way
also helps pointers that do exceed 4GB (e.g. prints from MMU config on
some arm64 systems) stand out better from the others.

individual elog_init() calls from mainboards that did them and automated
adding certain events through the boot state machine. Unfortunately,
the new code would sometimes not log any specific event at all, and
thereby also never call elog_init() (through elog_add_event()) which
adds the "System boot" event.
We can assume that any board that configures the eventlog at all
actually wants to use it, so let's just add another call to elog_init()
to the boot state machine so we can ensure it gets called at least once.

These Kconfig options provided a level of configurability that is
almost never necessary, so they are being moved into ordinary
preprocessor defines in elog_internal.h. The new threshold to
trigger shrinking is relative to the number of additional
(maximum-size) events that can fit, and the new target
post-shrink size is a percentage of the total ELOG area size.
BUG=chromium:467820
TEST=Add loop at the end of elog_init() that fills the ELOG area
to just below full_threshold with dummy events. Observe
successful shrinkage when the next event is logged.

CL:243671 moved the initialization of elog_initialized around, which is
now unfortunately so late that the ELOG_TYPE_BOOT event gets omitted
because the code believes the log to be broken at that time. Good thing
we now have a FAFT test for these things that I had of course been too
lazy to run. -.-
The real reason for moving that line was to put it after any point in
elog_init() that could still error out. The problem is that we might add
the "cleared" event before we try to shrink (which can fail and cause an
error)... but those two things cannot happen at the same time, so it
should be okay to flip them around and mark the elog as initialized in
between.

TEST=Ran firmware_EventLog on a Pinky, manually confirmed that I once
again get "System boot" events.

The elog driver has a really stupid bug that checks a result which is
stored in an unsigned variable for < 0. Surprisingly GCC does not catch
this nonsense right now, and I spent an hour trying out different
warning options without finding one that doesn't also bring a load of
stupid and unavoidable false positives (the biggest offender being
-Wtype-limits, which does exactly what we'd want except for flagging
things like if ((u8)var >= CONFIG_VAR_MIN) where the VAR_MIN Kconfig may
or may not be 0).
So, the only thing we can do is fix this one and wait for the next time
something like that blows up. -.- Also change some more code to make the
behavior more explicit (the old code already intended to work this way
since flash_base is statically initialized to 0, never assigned in the
error path and checked later in elog_init()... but there was an error
message that incorrectly claimed a different fallback behavior, and
explicitly assigning the values makes this easier to see). Finally, add
another state to the elog_initialized variable to avoid trying to
reinitialize a broken eventlog on every event (if it doesn't work the
first time, chances are that it won't work later on during the same boot
either).

TEST=Flashed Jerry with RO 6588.4 and RW 6588.23, observed how it now
cleanly enters recovery mode without blowing its bootblock away with
stray eventlog entries.
