We had the addrspace_32bit rdev in prog_loaders.c for a while to help
represent memory ranges as an rdev, and we've found it useful for a
couple of things that have nothing to do with program loading. This
patch moves the concept straight into commonlib/region.c so it is no
longer anchored in such a weird place, and easier to use in unit tests.
Also expand the concept to the whole address space (there's no real need
to restrict it to 32 bits in 64-bit environments) and introduce an
rdev_chain_mem() helper function to make it a bit easier to use. Replace
some direct uses of struct mem_region_device with this new API where it
seems to make sense.

This change moves all ACPI table support in coreboot currently living
under arch/x86 into common code to make it architecture
independent. ACPI table generation is not really tied to any
architecture and hence it makes sense to move this to its own
directory.
In order to make it easier to review, this change is being split into
multiple CLs. This is change 3/5 which basically is generated by
running the following command:
$ git grep -iIl "arch/acpi" | xargs sed -i 's/arch\/acpi/acpi\/acpi/g'

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.

Commit 0d9cd92e (chromeos: Clean up elog handling) removed the
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.
