While not implemented, copying the definitions from
later AGESA/AMD.h to older helps us avoid lots of
preprocessor directives.

CMOS isn't used that early, but the chipset initialization may be
required to access it.
In one instance, Intel Apollo Lake, the sanitize_cmos() function
seems to hang if called before bootblock_soc_early_init(). The
missing step is fast_spi_early_init(). But even without, one might
expect sanitize_cmos() to return eventually (it didn't within
about 20min).

In some cases we may have boards that need to differentiate SKUs but
don't really want to differentiate revisions (at least for some SKUs).
Let's add a compatible string match that includes only the SKU but not
the revision so that kernel DTSes don't have to specify every possible
revision if they want to match this.
This patch was adapted from depthcharge's http://crosreview.com/1512004

vtxprintf.c seems to have been written before string.h was as fleshed
out as it is today -- this patch removes some custom implementation of
stuff we now have globally. It also makes the skip_atoi() function
globally available, because I need it somewhere else, and while we maybe
don't want a huge fully-featured string parsing library in coreboot,
being able to parse an integer is occasionally useful.

coreboot should not have a definition of printf() anywhere -- it's too
easy to accidentally sneak it into code otherwise. Where that is needed
in code shared with userspace utilities, we should instead use printk()
and define a shim for that for the userspace side.

Libpayload has a family of functions that can "encode" or "decode" an
endian-specific integer onto a byte stream pointer. These allow writing
more pretty code than a raw be32_to_cpu/cpu_to_be32 with pointer casts
in many (de-)serialization scenarios, so let's add them to coreboot as
well.

This moves FSP1.1 to use postcar stage to tear down CAR.
On platforms with USE_GENERIC_FSP_CAR_INC the FSP header is found
during the postcar stage so there is no need to push to save it
in CAR global variables.
On FSP1.1 platforms with an open source CAR implementation (Skylake,
even though it still runs the FSP-T), the
soc/intel/common/blocks/cpu/car/exit_car.S code tears down CAR.
This also uses common functions to set up the MTRR to use after
CAR is torn down.
