As part of the documentation update on the changes made to the power
library for 19.05, information on SST-BF was added. This patch updates
the comment to clarify that a priority core is an SST-BF high
frequency core.

This patch adds a new bit in the capabilities mask that's returned by
rte_power_get_capabilities(), allowing application to query which cores
have the higher frequencies, and can then pin the workloads accordingly.
Returned Bits:
0 - Turbo Boost enabled
1 - Higher core base_frequency

Previously, in order to use the power library, it was necessary
for the user to disable the intel_pstate driver by adding
“intel_pstate=disable” to the kernel command line for the system,
which causes the acpi_cpufreq driver to be loaded in its place.
This patch adds the ability for the power library use the intel-pstate
driver.
It adds a new suite of functions behind the current power library API,
and will seamlessly set up the user facing API function pointers to
the relevant functions depending on whether the system is running with
acpi_cpufreq kernel driver, intel_pstate kernel driver or in a guest,
using kvm. The library API and ABI is unchanged.

Since this patch-set attempts to clean up the power library,
and there are many instances of "unsigned" caught by checkpatch,
it was decided to clean these up first rather than have them included
in the later patches in the patch set. And would also minimise this
type of error being caught by checkpatch in the future

Moved the current librte_power implementation to rte_power_acpi_cpufreq, with
renaming of functions only.
Added rte_power_kvm_vm implementation to support Power Management from a VM.
librte_power now hides the implementation based on the environment used.
A new call rte_power_set_env() can explicidly set the environment, if not
called then auto-detection takes place.
rte_power_kvm_vm is subset of the librte_power APIs, the following is supported:
rte_power_init(unsigned lcore_id)
rte_power_exit(unsigned lcore_id)
rte_power_freq_up(unsigned lcore_id)
rte_power_freq_down(unsigned lcore_id)
rte_power_freq_min(unsigned lcore_id)
rte_power_freq_max(unsigned lcore_id)
The other unsupported APIs return -ENOTSUP
