This patch calculates two power attributess, i.e. limits and demands
for power distribution. Traversing the breadth first tree bottom up,
this calculates the attribute of each domain based on
following calculation,

domain limit = min(children limit, own limit)
domain demand = max(children demand, own demand)

Create a common core file that can be used by fast channels and
normal SCMI Power Capping protocol commands.

The common core file will handle the interactions with power
capping HAL and handle SCMI agents' requests synchronisation
between normal commands and fast channels.

The change would simplify the implementation and make the
module easier to extend.

Changes to fast channels are done in the next patch.

The renaming was carried out as perf controller use cases
grow larger, its components names need to be renamed to adapt
to the new use cases. The blocks core and cluster would be
renamed limiter and controller domain to avoid confusion and to
be more generic.

The controller domain in the system consists of various performance
limiters and applies the lowest performance limit across the domain.

Some unit tests in mod_dvfs_unit_test.c initialise local data
structures with the minimum information required to test DVFS
functions.

The local data structures sometimes have pointers in them that
depending on the particular test being run - should also be
initialised, but in some cases the unit test failed to do that.

This resulted in some pointers being initialised with whatever
random data was on the stack and depending on what ended in those
pointers, accessing data fields through them could end in a segfault.

The fix makes sure all pointers that need initialising are
properly set.

Apply PID feedback on Power Cap requested by the agent as follows:
1) The set point is the requested cap by the agent.
2) The feedback is the average measured power.
3) The output is a power limit that is delivered to the power distributor.

The usage of the PID would allow the Power Cap not to be set directly
to the system although a margin would be there to allow bursts of performance
applied on the system for a short period of time.

The PID is called continuously on intervals inside the get_power_limit function
called from metrics_analyzer.
