Picasso neither has the corresponding P_CNT register implemented nor
writes a _PTC ACPI object that would specify the P_CNT register. The
Picasso UEFI reference code also sets the duty_width FADT entry to 0.
This also aligns the Picasso code with the Cezanne code in this regard.

The latency values in the _CST package override the values in the
p_lvl2_lat and p_lvl3_lat FADT fields. In Picasso, Cezanne, Mendocino,
Phoenix and Glinda generate_cpu_entries generates the _CST packages for
each CPU device. The coreboot code for Stoneyridge doesn't generate _CST
packages for the CPU objects, but those are provided via the PSTATE SSDT
binaryPI generates and agesa_write_acpi_tables gets and adds to the ACPI
tables. The AGESA reference code also sets those two FADT entries to the
equivalents of ACPI_FADT_C2_NOT_SUPPORTED and ACPI_FADT_C3_NOT_SUPPORTED
so this also matches the AGESA behavior.
From the ACPI 6.4 spec: "Values provided by the _CST object override
P_LVLx values in P_BLK and P_LVLx_LAT values in the FADT."

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.

Stoneyridge used CONFIG_MAX_CPUS and CONFIG_MAX_CPUS + 1 directly as
IOAPIC IDs and Picasso had Kconfig options to configure that, but still
used the common SMBus controller code that used CONFIG_MAX_CPUS as ID
for the FCH IOAPIC. If a board overrides the PICASSO_FCH_IOAPIC_ID
Kconfig option to a value that isn't CONFIG_MAX_CPUS, we'll get a
mismatch between the ID that gets written into the FCH IOAPIC register
and the ID in the corresponding ACPI table. In order to avoid that add
defines to each SOC's southbridge.c and use them in all soc/amd code.
