refactor(smccc): move pmf to vendor el3 calls

Move pmf support to vendor-specific EL3 Monitor Service Calls. Remove
pmf call count as it's not supported in vendor-specific el3 as per
SMCCC Documentation 1.5:
https://developer.arm.com/documentation/den0028/latest

Add a deprecation notice to inform PMF is moved from arm-sip range to
vendor-specific EL3 range. PMF support from arm-sip range will be
removed and will not available after TF-A 2.12 release.

fix(smccc): ensure that mpidr passed through SMC is valid

There are various SMC calls which pass mpidr as an argument which is
currently tested at random places in SMC call path.
To make the mpidr validation check consistent across SMC calls, do
this check as part of SMC argument validation.

This patch introduce a helper function is_valid_mpidr() to validate
mpidr and call it as part of validating SMC arguments at starting of
SMC handlers (which expect mpidr as an argument).

Sanitise includes across codebase

Enforce full include path for includes. Deprecate old paths.

The following folders inside include/lib have been left unchanged:

- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}

The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).

For example, this patch had to be created because two headers were
called the same way: e0ea0928d5b7 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a282 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca33988b9 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.

Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

Convention. The correct acronym is SMCCC. This affects a few definitions

Some files have been renamed (smcc.h, smcc_helpers.h and smcc_macros.S)
but the old files have been kept for compatibility, they include the
new ones with an ERROR_DEPRECATED guard.

Add Performance Measurement Framework(PMF)

This patch adds Performance Measurement Framework(PMF) in the
ARM Trusted Firmware. PMF is implemented as a library and the
SMC interface is provided through ARM SiP service.

The PMF provides capturing, storing, dumping and retrieving the
time-stamps, by enabling the development of services by different
providers, that can be easily integrated into ARM Trusted Firmware.
The PMF capture and retrieval APIs can also do appropriate cache
maintenance operations to the timestamp memory when the caller
indicates so.

`pmf_main.c` consists of core functions that implement service
registration, initialization, storing, dumping and retrieving
the time-stamp.
`pmf_smc.c` consists SMC handling for registered PMF services.
`pmf.h` consists of the macros that can be used by the PMF service
providers to register service and declare time-stamp functions.
`pmf_helpers.h` consists of internal macros that are used by `pmf.h`

By default this feature is disabled in the ARM trusted firmware.
To enable it set the boolean flag `ENABLE_PMF` to 1.

NOTE: The caller is responsible for specifying the appropriate cache
maintenance flags and for acquiring/releasing appropriate locks
before/after capturing/retrieving the time-stamps.
