tools/power/x86/intel-speed-select: Avoid duplicate Package strings for json

For platforms where multiple packages/die, this makes "Package-" key
duplicate. To make unique, add die and cpu id to key name.

So "Package-0" key name will change to "Package-0-die-x:cpu-x".

For example:
$sudo ./intel-speed-select -f json perf-profile info
Intel(R) Speed Select Technology
Executing on CPU model:106[0x6a]
{
"package-0:die-0:cpu-0": {
"perf-profile-level-0": {
"cpu-count": "32",
"enable-cpu-count": "32",
...
...

"perf-profile-level-0": {
"cpu-count": "32",
"enable-cpu-count": "32",
"enable-cpu-mask": "ffff0000,ffff0000",
...
...

For non json format, there is no change. Here when print_package_info()
is called, it will return the level to print for other information.

There are two instances of “speed-select-turbo-freq” underneath

Result is that we can only access:

"high-priority-max-avx2-frequency(MHz)": "2800",

The turbo-freq enable with auto mode, prints result for the last possible
CPU, which is not correct when either CPU is not present or user wants

below command user wants to limit to die/package 0, but the
"turbo-freq --auto" result is displayed using the other package.

Intel(R) Speed Select Technology
package-0
die-0
cpu-0
turbo-freq

Since we do have to traverse all CPUs, don't display CPU info for
"turbo-freq --auto", as we already displayed the result for
turbo-freq enable with the CPU information.

With the fix, the same command results in:

$ sudo intel-speed-select -c 0 turbo-freq enable -a

"tools/power/x86/intel-speed-select: Output success/failed for command

Here the get-config-levels is interpreted as error and displayed
as error with the above commit:

package-1

get-config-levels:failed(error 4)

tools/power/x86/intel-speed-select: Change turbo ratio output to maximum turbo frequency

The intel-speed-select tool currently outputs the turbo ratio for every
bucket. Make the output more user-friendly by changing the output to the
maximum turbo frequency.

tools/power/x86/intel-speed-select: Switch output to MHz

These features are introduced on new processors that will never operate
in the KHz range.

Save some zeros and switch the output to MHz.

tools/power/x86/intel-speed-select: Simplify output for turbo-freq and base-freq

The current output of 'intel-speed-select -c 53 perf-profile info -l 0'
shows

speed-select-turbo-freq-support:1
speed-select-base-freq-support:1
speed-select-base-freq-enabled:0
speed-select-turbo-freq-enabled:0

Simplify the output to single lines displaying status of disabled,
enabled, and unsupported.

tools/power/x86: A tool to validate Intel Speed Select commands

The Intel(R) Speed select technologies contains four features.

Performance profile:An non architectural mechanism that allows multiple
optimized performance profiles per system via static and/or dynamic
adjustment of core count, workload, Tjmax, and TDP, etc. aka ISS
in the documentation.

Base Frequency: Enables users to increase guaranteed base frequency on
certain cores (high priority cores) in exchange for lower base frequency
on remaining cores (low priority cores). aka PBF in the documenation.

Turbo frequency: Enables the ability to set different turbo ratio limits
to cores based on priority. aka FACT in the documentation.

Core power: An Interface that allows user to define per core/tile
priority.

There is a multi level help for commands and options. This can be used
to check required arguments for each feature and commands for the
feature.

To start navigating the features start with

$sudo intel-speed-select --help

For help on a specific feature for example
$sudo intel-speed-select perf-profile --help

To get help for a command for a feature for example
$sudo intel-speed-select perf-profile get-lock-status --help
