In CB:71614 Kyösti pointed out that ACPI_GPE0_BLK is the wrong address
to assign to proc_blk_addr; the correct one would be ACPI_CPU_CONTROL.
When looking a bit closer into this, it turned out that
acpigen_write_processor is generating deprecated AML opcodes, so replace
the acpigen_write_processor call with a call to the newly added
acpigen_write_processor_device function that also doesn't have the
proc_blk_addr and proc_blk_len parameters. The information about the IO
port for entering C-states is already written into an SSDT by
acpigen_write_CST_package which is likely also the reason why the wrong
proc_blk_addr value wasn't noticed for a very long time.
TEST=Mandolin still boots Ubuntu 22.04 LTS and Windows 10 and no
possibly related errors show up. Linux gets the expected C-state
information from the _CST package inside the processor device scope.

The ACPI PROCESSOR_OP has been deprecated in ACPI 6.0 and dropped in
ACPI 6.4 and is now permanently reserved. As a replacement, DEVICE_OP
with the special HID ACPI0007 should be used instead. This special HID
was introduced in version 3 of the ACPI spec. To have a function to
generate this, acpigen_write_processor_device is introduced. The CPU
index is used as UID which can be assumed to be unique.

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 :(
