The cpufreq subsystem has a generic sysfs interface for controlling boost
(/sys/devices/system/cpu/cpufreq/boost).
The sysfs interface can be used to enable boost control from the cpupower
command on non-x86 platforms as well. So, allow boost controlling
on non-x86 system if boost sysfs file exists.

The set subcommand enables/disables the boost feature using the following
syntax:
    cpupower set --boost 1
    cpupower set --boost 0

The --boost option is an alias for --turbo-boost. We provided the neutral
option name because the name "turbo boost" is specific to Intel technology.

The frequency-info subcommand displays the enabled/disabled state of
the boost feature as follows:
    boost state support:
        Active: yes (or no)

The set subcommand's -t option is documented as being available for boost
configuration, but it was not actually functioning due to a bug
in the option handling.

/sys/devices/system/cpu/intel_uncore_frequency/package_X_die_Y/
may be readable by all, but
/sys/devices/system/cpu/intel_uncore_frequency/package_X_die_Y/current_freq_khz
may be readable only by root.

Non-root turbostat users see complaints in this scenario.

Fail probe of the interface if we can't read current_freq_khz.

Together with the RAPL MSRs, there are more MSRs gone on DMR, including
PLR (Perf Limit Reasons), and IRTL (Package cstate Interrupt Response
Time Limit) MSRs. The configurable TDP info should also be retrieved
from TPMI based Intel Speed Select Technology feature.

Remove the access of these MSRs for DMR. Improve the DMR platform
feature table to make it more readable at the same time.

External atributes with format "raw" are not printed in summary lines

behaves like "raw" but also adds the summary data

pkg_base[pkg_id] is a simple array of structure pointers,
let the compiler treat it that way.
