Implement an optional callout for AgesaHeapRebase which allows AGESA
to override any internal hardcoded heap addresses.
Designate a region in CAR that may be used for pre-mem heap and return
that address before DRAM is configured. After DRAM is up, the address
in cbmem is returned.

Implement a new AGESA callout that may be used to find the correct
temporary location in DRAM to store heap data.
Near the end of AmdInitPost, AGESA migrates its heap from a CAR-based
location to a temporary region. Once cbmem has been established, the
heap will be relocated again in AmdInitEnv from the temp location to
the final one.
This patch does not materially affect the behavior of AGESA's heap
management. It only puts coreboot in control of the location. Future
work may refactor the copying.

Add a new callout definition for AgesaGetTempHeapBase and displace
AgesaHeapRebase (which was merged too soon) in the ordering. Also
add its structure.
AGESA will be modified to ask coreboot for the location for temporary
storage of heap data at the end of InitPost. The old methodology is
to use 0xb0000 but the change will allow coreboot to determine the
location.

The -S flag of me_cleaner, in addition to the standard code removal,
sets the the AltMeDisable bit (ME 6.x-10.x) or the HAP bit (ME 11.x),
which asks Intel ME to stop the execution after the hardware
initialization.
This should bring some advantages:
* The state of Intel ME can be easily obtained by reading the Current
Operation Mode register to trigger specific adjustments in the
raminit (as already done in bd82x6x)
* Intel ME falls into a more defined state, instead of being in a
generic "Image Failure"
* Hopefully, less code is run by Intel ME, as the execution should
stop before even trying to load additional modules
Tested on:
* Nehalem, Sandy Bridge and Ivy Bridge (Nicola Corna)
* Broadwell, Skylake and Kabylake (Youness Alaoui)
If needed, the -S flag can be removed or integrated with other
board-specific options by overriding CONFIG_ME_CLEANER_ARGS.

1. Updates root device and bus names to add base_ prefix.
2. Adds a function parse_devicetree that sets the root_parent and
linenum before calling yyparse().
3. Updates all uses of root_dev to refer to the next base_root_dev.

This change re-factors the device structure in parse tree to be able
to support multidev devices just like non-multidev devices.
With this change, every device has a bus under it which is the parent
of all devices that fall on the bus. If there are duplicate entries in
the devicetree, then there will be multiple buses under the device and
each bus will have its own set of children.
The tree starts out with a root device which has a root bus under
it. This is a special device which is created statically and its
parent is its own root bus. When parsing the device tree file, devices
get added under the root bus as children.
Since this change re-organizes the way devicetree is represented, it
gets rid of latestchild and next_sibling pointers from struct
device. Also, the tree traversal to generate static.c is changed to
breadth-first walk instead of using the next_sibling.

Looking at the 100MHz signal, we were violating the timing requirements.
66MHz still isn't great, but it's a good tradeoff between improving
the signal and losing boot speed time.
This slows down the boot time by about 20mS.
BUG=b:109583457
TEST=Boot grunt, look at signal on scope
