This register isn't used in coreboot and isn't defined in the Picasso
PPR #55570 Rev 3.18.
To enter a lower C-state, a read request to a special IO port is done.
The base address of this group of IO ports is configured in
set_cstate_io_addr via the MSR_CSTATE_ADDRESS and that read won't leave
the CPU. IIRC trying to put the MMIO mapping for entering the lower
C-states into the _CST package didn't work as expected when it was tried
on I think Cezanne.

This patch moves ME host firmware status register structures to ME
header file. It also marks unused structure fields to reserved.
The idea here is to decouple ME specification defined structures from
the source file `.c` and keep those into header files so that in future
those spec defined header can move into common code.
The current and future SoC platform will be able to select the correct
ME spec header based on the applicable config. It might be also
beneficial if two different SoC platforms would like to use the same
ME specification and not necessarily share the same SoC directory.

It turns out that the [0xfa000000-0xfaffffff] range conflicts with
some North TraceHub address space ranges ([0xfad00000-0xfadfffff] and
[0xfacfc000-0xfacfffff]).
Experiments have established that this conflicting range results in an
unpected PIPE A underrun issue reported by i915 and some visible
flickers on the display during boot.
The [0xf0000000-0xffffffff] range is a crowded memory space with
resources statically assigned to some devices but also some ranges
used at various point in the boot flow by the FSP.
To not run into any other potential conflicts, we want to pick a
unused memory space. But at this early stage of the boot, we do not
have full knowledge of what memory space is going to be used by the
FSP. As a result, we decided to pick the [0xaf000000-0xafffffff] range
as:
1. It does not conflicting with any coreboot memory space usage
2. It is the address the FSP uses by default for GFX MMIO BAR0 and as
such should not conflict with any FSP memory space usage.

This functionality is used in multiple places, so factor it out into a
function. Compared to acpigen_write_processor_cnot, the buffer size is
decreased from 40 to 16 bytes, but the format string specified by
CONFIG_ACPI_CPU_STRING results in 9 chars and a NULL byte which will fit
into the buffer without any issue. I've seen the CPU devices being put
into another scope within \_SB, but even in that case that would be 14
chars and a NULL byte whist still fits into the 16 byte buffer. For
acpigen_write_processor and acpigen_write_processor_package this doesn't
change any edge case behavior. In the unrealistic case of the format
string resulting in a longer CPU device string, this would have been a
problem before this patch too.
Also drop the curly braces of the for loop in
acpigen_write_processor_package. This makes the code a bit harder to
read and isn't a very good idea, but with the curly braces in place, the
linter breaks the build :(

The Alder Lake PEIM graphics driver executed as part of the FSP does
not wait for the panel power cycle to complete before it initializes
communication with the display. It can result in AUX channel
communication time out and PEIM graphics driver failing to bring up
graphics.
If we have performed some graphics operation in romstage, it is
possible that a panel power cycle is still in progress. To prevent any
issue with the PEIM graphics driver it is preferable to ensure that
panel power cycle is complete.

We were using the libgfxinit `Initialize' function with the
`Clean_State' parameter because the more appropriate `Update_Output'
function was not performing all the necessary clean up operations for
the PEIM driver to be successful when libgfxinit was used in romstage.
Thanks to a lot of experiments and some log analysis efforts, we were
able to identify the missing operation and fix the `Update_Output'
function (cf. https://review.coreboot.org/c/libgfxinit/+/72123).
The `initialized' global variable is now unnecessary as we track the
initialization in the Ada code instead.
Since the `Update_Output' function does not return any value, this
patch modifies the `gma_gfxstop' prototype accordingly. This does not
have any impact as the return value was not used anyway.
