Merge branch 'intel_idle+acpi'

Merge changes updating the ACPI processor driver in order to export
acpi_processor_evaluate_cst() to the code outside of it and adding
ACPI support to the intel_idle driver based on that.

* intel_idle+acpi:
Documentation: admin-guide: PM: Add intel_idle document
intel_idle: Use ACPI _CST on server systems
intel_idle: Add module parameter to prevent ACPI _CST from being used
intel_idle: Allow ACPI _CST to be used for selected known processors
cpuidle: Allow idle states to be disabled by default
intel_idle: Use ACPI _CST for processor models without C-state tables
intel_idle: Refactor intel_idle_cpuidle_driver_init()
ACPI: processor: Export acpi_processor_evaluate_cst()
ACPI: processor: Make ACPI_PROCESSOR_CSTATE depend on ACPI_PROCESSOR
ACPI: processor: Clean up acpi_processor_evaluate_cst()
ACPI: processor: Introduce acpi_processor_evaluate_cst()
ACPI: processor: Export function to claim _CST control

ACPI: processor: Export acpi_processor_evaluate_cst()

The intel_idle driver will be modified to use ACPI _CST subsequently
and it will need to call acpi_processor_evaluate_cst(), so move that
function to acpi_processor.c so that it is always present (which is
required by intel_idle) and export it to modules to allow the ACPI
processor driver (which is modular) to call it.

No intentional functional impact.

ACPI: processor: Export function to claim _CST control

The intel_idle driver will be modified to use ACPI _CST subsequently
and it will need to notify the platform firmware of that if
acpi_gbl_FADT.cst_control is set, so add a routine for this purpose,
acpi_processor_claim_cst_control(), to acpi_processor.c (so that it
is always present which is required by intel_idle) and export it
to allow the ACPI processor driver (which is modular) to call it.

No intentional functional impact.

Pull ACPI updates from Rafael Wysocki:
"These include an ACPICA update (to upstream revision 20190816),
improvements of support for memory hot-add in the HMAT handling code
and some assorted fixes and cleanups.

Specifics:

- Update the ACPICA code in the kernel to upstream revision 20190816
including:
* Internal limits change to support larger systems (Bob Moore).
* Macros clean up (Bob Moore).
* printf format string fixes (Bob Moore).
* Full deployment of the ACPI_PRINTF_LIKE macro (Bob Moore).
* Tools improvements (Bob Moore, Colin Ian King).
* Windows _OSI support fixes (Jung-uk Kim).

- Improve memory hot-add support in the ACPI HMAT handling code (Dan
Williams, Keith Busch).

- Fix the ACPI LPSS (Low-Power Subsystem) driver for Intel SoCs to
save and restore private registers during system-wide suspend and
resume on systems with the Lynxpoint PCH (Jarkko Nikula).

- Convert the ACPI documentation related to LEDs to ReST (Sakari
Ailus).

- Fix assorted issues and make assorted minor improvements in the
ACPI-related code (Al Stone, Andy Shevchenko, Jiri Slaby, Kelsey
Skunberg, Krzysztof Wilczynski, Liguang Zhang, Wenwen Wang,
YueHaibing)"

ACPI / processor: don't print errors for processorIDs == 0xff

Some platforms define their processors in this manner:

Name (_UID, "CPUSCK0") // _UID: Unique ID

Processor (CP01, 0x02, 0x00000410, 0x06){}
Processor (CP02, 0x04, 0x00000410, 0x06){}

Processor (CP0A, 0xFF, 0x00000410, 0x06){}
Processor (CP0B, 0xFF, 0x00000410, 0x06){}
...

The processors marked as 0xff are invalid, there are only 8 of them in
this case.

So do not print an error on ids == 0xff, just print an info message.
Actually, we could return ENODEV even on the first CPU with ID 0xff, but
ACPI spec does not forbid the 0xff value to be a processor ID. Given
0xff could be a correct one, we would break working systems if we
returned ENODEV.
