The code in cpu/intel/car/romstage.c Does most of the things like
setting up timestamps, stack guards, entering postcar.
A functional difference is that the FSP header is searched for twice
instead of passed from the CAR entry to the C code. When using
C_ENVIRONMENT_BOOTBLOCK this needs to be done anyway (or a special
linker symbol kept across multiple stages is needed, which is likely
not worth the speedup).

FDT property data should not be const -- sometimes we need to update it,
for example when fixing up phandles in an overlay. On the other hand
it's occasionally desirable to put a string constant in there without
having to strdup() it all the time... let's just live with the tiny
implicit assumption that the data we'd want to modify (phandle
references, mostly) will never be added from string constants, and put a
cast in dt_add_string_prop().

This patch updates the device tree dumping functions (not compiled by
default but available for debugging) to output properties and nodes in a
format similar to .dts files that is very close to what dtc outputs when
you decompile a .dtb with it. This makes it easier to match device tree
dumps from coreboot with device tree dumps generated by other device
tree tooling.

Currently DT paths are *not* expected to start with '/'. This is not
what the spec says (see Devicetree Specification v0.2, 2.2.3 Path Names)
and also not what is done by Linux.
Change dt_find_node_by_path() to expect paths to start with '/' and add
a leading '/' to all DT path strings. Besides the compatibility with the
spec this change is also needed to support aliases in the future.

Besides looking up a node with an absolute path dt_find_node_by_path()
currently also supports finding a sub-node of a non-root node. All
callers of the function pass the root node though, so it seems there
is no real need for this functionality. Also it is planned to support
DT path names with aliases, which would become messy in combination with
the lookup from a sub-node.
Change the interface of dt_find_node_by_path() to receive the DT tree
object instead of a parent node and adapt all callers accordingly.

This patch caches phandles when unflattening the device tree, so we
don't have to look up the phandle property again every time we're trying
to find the phandle of a node. This is especially important when
supporting phandle lookups, which are also added. In addition we keep
track of the highest phandle in the whole tree, which will be important
for applying overlays later.
With this, dt_get_phandle(node) becomes obsolete because the phandle is
already available as a member variable in the node.

The FIT code is already using xzalloc() everywhere, and that's the only
real consumer of device tree code right now. Chances are if you're
trying to unflatten an FDT and it doesn't fit into the heap you're
pretty much screwed anyway, so all the OOM handling feels a bit
unnecessary (and some functions will just silently fail because they
don't have a return value, which is bad). Let's just switch this all to
die on failed allocations.
