This includes a huge set of refactorings to support Core Display Clock
(CDClk) frequency switching based on the current mode requirements.
The CDClk is configurable since Haswell and runtime switching is suppor-
ted since Broadwell. Always using the lowest possible frequency setting
should allow some power-savings. While, on the upper end, we can support
higher resolution panels now, without having to change the static confi-
guration.
There have also been some smaller changes and fixes, including:
o Parsing of eDP 1.4+ DPCD link rates, enables panels that don't
advertise a maximum link rate but only individual ones.
o DP support for Ibex Peak.
o Corrected limit for HDMI on G45 to 165MHz.
o Reworked GMBUS reset handling and timeouts, should help with
stalled GMBUS controllers when unimplemented ports were probed
by accident.
Tested on various boards from GM45 to KBL-R.

The i82801ix_early_init is now called both in the bootblock and
romstage. The rationale behind setting this up twice is to ensure
bootblock-romstage compatibility in the future if for instance VBOOT
is used.
This moves the console init to the bootblock.
The romstage now runs uncached. Adding a prog_run hooks to set up an
MTRR to cache the romstage will be done in a followup patch.
The default size of 64KiB is not modified for the bootblock as trying
to fit both EHCI and SPI flash debugging needs a more space and 64KiB
is the next power of 2 size that fits it.
TESTED on Thinkpad X200.

With CONFIG_C_ENVIRONMENT_BOOTBLOCK it makes more sense to rely on the
size of the bootblock over CONFIG_XIP_ROM_SIZE. To make this work,
only powers of 2 are allowed as bootblock size.

If a device node should be enabled on some variants, but disabled on
others, it had better be declared as disabled (rather than absent) in
base device tree (rather than override tree for the variant disabling
it), and enabled in override tree for the variant needing it, so that
it does not need to be declared once more when adding another variant
with such node disabled.

So, this is odd in multiple ways. First of all, we fix something:
We work around a weirdness in `make oldconfig` that adds spurious
entries into the `auto.conf` for choices that were given a symbol
name.
When introducing the Ada config package, it seemed reasonable to
use `auto.conf` as source, but it turned out that we didn't use it
as input, only `config.h` and the original `.config` were used. As
the syntax for `.config` is the same as for `auto.conf` we use the
former now as input for Ada, too. One question remains: If `.config`
already contains all required information, what is this `auto.conf`
and what does it want?
Alternatively, we could try to fix `oldconfig` or add a linter to
forbid named choices. I thought, our build test would reject the
latter already. But the `oldconfig` behaviour is too subtle.
We keep a dependency on the `oldconfig` step, to make sure it runs
first.

New changes in the latest binutils 2.32 lead to assembler errors causes
ipxe build failure. IPXE uses the divide test which requires /dev/null as
input as well as the output file name.
This patch facilitates the /dev/null as an exception to the current
changes in binutils package while building crossgcc for coreboot leads to
successful build of ipxe and further tests to pass based on /dev/null and
applies automatically during the crossgcc rebuild.
Also, this can be reverted once binutils/ipxe provides an updated release
in this respect.

Remove the calculation of the Reserved Intel MMIO Memory size from
systemagent and memmap, since it is not needed.
The size is used in SA to calculate the space between cbmem_top and TSEG
without DPR and Chipset Reserved Memory. Since this will always be equal
to 0, the reservation will be skipped and TSEG, DPR and Chipset Reserved
Memory will get reserved alltogether.
By reading the code and pratical testing we figured out that:
- TSEG - DPR - reserved - top_of_memory == 0
- TSEG - DPR - reserved == top_of_memory
This means the whole block will never reserve anything because it is
always 0. Hence the code can be removed for simplification.
