ACPI: processor: Get rid of ACPICA message printing

The ACPI_DEBUG_PRINT() and ACPI_EXCEPTION() macros are used for
message printing in the ACPICA code and they should not be used
elsewhere. Special configuration (either kernel command line or
sysfs-based) is needed to see the messages printed by them and
the format of those messages is also special and convoluted.

For this reason, replace all of the ACPI_DEBUG_PRINT() and
ACPI_EXCEPTION() instances in the ACPI processor driver with
corresponding dev_*(), acpi_handle_*() and pr_*() calls depending
on the context in which they appear.

Also drop the ACPI_PROCESSOR_COMPONENT definition that is not going
to be necessary any more.

ACPI: processor: remove comment regarding string _UID support

ACPI 6.3 Errata A no longer allows _UID to return a string except for
Itanium (for historical reasons) as stated in section 5.2.12:

"From ACPI Specification 6.3 onward, all processor objects for all
architectures except Itanium must now use Device() objects with an
_HID of ACPI0007, and use only integer _UID values."

Therefore, the "we don't handle string _UIDs yet" comment, which
implies a missing feature, is redundant, so drop it.

Merge tag 'pm-5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management updates from Rafael Wysocki:
"These rework the collection of cpufreq statistics to allow it to take
place if fast frequency switching is enabled in the governor, rework
the frequency invariance handling in the cpufreq core and drivers, add
new hardware support to a couple of cpufreq drivers, fix a number of
assorted issues and clean up the code all over.

Specifics:

- Rework cpufreq statistics collection to allow it to take place when
fast frequency switching is enabled in the governor (Viresh Kumar).

- Make the cpufreq core set the frequency scale on behalf of the
driver and update several cpufreq drivers accordingly (Ionela
Voinescu, Valentin Schneider).

- Add new hardware support to the STI and qcom cpufreq drivers and
improve them (Alain Volmat, Manivannan Sadhasivam).

- Fix multiple assorted issues in cpufreq drivers (Jon Hunter,
Krzysztof Kozlowski, Matthias Kaehlcke, Pali Rohár, Stephan
Gerhold, Viresh Kumar).

- Fix several assorted issues in the operating performance points
(OPP) framework (Stephan Gerhold, Viresh Kumar).

- Allow devfreq drivers to fetch devfreq instances by DT enumeration
instead of using explicit phandles and modify the devfreq core code
to support driver-specific devfreq DT bindings (Leonard Crestez,
Chanwoo Choi).

- Improve initial hardware resetting in the tegra30 devfreq driver
and clean up the tegra cpuidle driver (Dmitry Osipenko).

- Update the cpuidle core to collect state entry rejection statistics
and expose them via sysfs (Lina Iyer).

- Improve the ACPI _CST code handling diagnostics (Chen Yu).

- Update the PSCI cpuidle driver to allow the PM domain
initialization to occur in the OSI mode as well as in the PC mode
(Ulf Hansson).

- Rework the generic power domains (genpd) core code to allow domain
power off transition to be aborted in the absence of the "power
off" domain callback (Ulf Hansson).

- Fix two suspend-to-idle issues in the ACPI EC driver (Rafael
Wysocki).

- Fix the handling of timer_expires in the PM-runtime framework on
32-bit systems and the handling of device links in it (Grygorii
Strashko, Xiang Chen).

- Add IO requests batching support to the hibernate image saving and
reading code and drop a bogus get_gendisk() from there (Xiaoyi
Chen, Christoph Hellwig).

- Allow PCIe ports to be put into the D3cold power state if they are
power-manageable via ACPI (Lukas Wunner).

- Add missing header file include to a power capping driver (Pujin
Shi).

- Clean up the qcom-cpr AVS driver a bit (Liu Shixin).

- Kevin Hilman steps down as designated reviwer of adaptive voltage
scaling (AVS) drivers (Kevin Hilman)"
