The log messages in processor_perflib.c is not in consistency,
we have some printk() calls with PREFIX, but some are not; we
use pr_*() functions without prefix. So add pr_fmt() and unify
them with pr_*() functions.

While at it, fix some obvious coding style issues when going
through the functions.

Quite a few users of ACPI objects want to log a warning message if
the evaluation fails which is a repeating pattern, so introduce a
helper function for that purpose and convert some code where it is
open-coded to using it.

No intentional functional impact.

One of the "status != AE_NOT_FOUND" checks in
acpi_processor_get_platform_limit() is redundant,
so rearrange the code to eliminate it.

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.

 "These update the CPPC cpufreq driver and intel_pstate (which involves
  updating the cpufreq core and the schedutil governor) and make
  janitorial changes in the ACPI code handling processor objects.

  Specifics:

   - Rework the passive-mode "fast switch" path in the intel_pstate
     driver to allow it receive the minimum (required) and target
     (desired) performance information from the schedutil governor so as
     to avoid running some workloads too fast (Rafael Wysocki).

   - Make the intel_pstate driver allow the policy max limit to be
     increased after the guaranteed performance value for the given CPU
     has increased (Rafael Wysocki).

   - Clean up the handling of CPU coordination types in the CPPC cpufreq
     driver and make it export frequency domains information to user
     space via sysfs (Ionela Voinescu).

   - Fix the ACPI code handling processor objects to use a correct
     coordination type when it fails to map frequency domains and drop a
     redundant CPU map initialization from it (Ionela Voinescu, Punit
     Agrawal)"

For errors parsing the _PSD domains, a separate domain is returned for
each CPU in the failed _PSD domain with no coordination (as per previous
comment). But contrary to the intention, the code was setting
CPUFREQ_SHARED_TYPE_ALL as coordination type.

Change shared_type to CPUFREQ_SHARED_TYPE_NONE in case of errors parsing
the domain information. The function still returns the error and the caller
is free to bail out the domain initialisation altogether in that case.

Given that both functions return domains with a single CPU, this change
does not affect the functionality, but clarifies the intention.
