Miscellaneous SCMI v3.0 fixes

See merge request !36

Add an optional mechanism for relaxed protocol versioning checks in order
to let some testcases be run also against an SCMI server platform which
advertises a specific protocol version greater than the one currently
supported by the test suite.

Relaxed version checks support is currently optionally configurable only
for linux platform using a command option.
Note that, by default, strict version checking is instead carried on, as
it was before.

Optional relaxed protocol versioning checks support is then added to Base,
Performance, Power and Reset

Some tests depends on others since they depends on sensor data collected
by early tests; moreover some tests require a minimum major protocol
version to be run but they can also be run successfully on any following
newer major protocol version.

Fix ordering of tests and minimum version requirements.

SCMIv3.0 Sensor descriptors have variable lengths based on the presence
or not of extended attributes; the presence of extended attributes is
NOT mandatory though even in SCMIv3.0 messages, so that, within the same
reply you could received a mix of sensor descriptors carrying or NOT the
extended attributes: as a consequence the array of sensor descriptors is
composed of variable length elements and as such must be parsed.

When querying number of supported protocols and number of agents supported
by the backend SCMI server under test take care to save such information
before any comparison is made against the expected values for the specific
target at hand.

This will allow us to possibly define a new target platform with relaxed
expectations and just proceed to test any supported protocols it is found.

Many testcases covers the scenario in which invalid SCMI command IDs are
used: these are generally defined as one-off the last valid known command
ID; now that SCMIv3.1 spec is published all valid v3.1. commands, for all
the protocols supported by this suite, should be enumerated properly to
avoid using by mistake a valid command ID as an invalid one in case the
SCMI backend server under test already supported it.

Add Linux app helpers to map physical to virtual addresses

See merge request !35

Use common helpers to properly map SCMI-server provided FCs physical
addresses to virtual ones before accessing them on Linux test app.

Some tests require to access some physical memory addresses as advertised
by the SCMI backend server (e.g. FastChannels).

When running the Linux test app, such physical memory needs to be properly
mapped in the virtual address space of the test suite process in order to
be accessible.

Non-Linux test apps behaviour is left unchanged.

test_c007: correct processing of triplet rate arrays

See merge request !33

The test incorrectly accesses triplet rate arrays
by going out of bounds due to a incorrectly used
increment variable. This is replaced by fixed indexes
outside of the previous loop.

perf/test_d007: Update logic for intermediate level

See merge request !25

Test 007 iterates over the performance levels discovered to find min,
max and intermediate. The intermediate level is chosen to be the second
one found. In domains where there are only 2 levels the intermediate
level is in fact the max.
In further tests, the intermediate level is chosen to replace the max,
while effectively the value used is the max, thus nullifying the test
case.

This patch adds an extra check to pick the minimum level as
intermediate when a performance domain exposes only two levels.

Add TC0 hardware under Linux platform

See merge request !24

Restructured the directories under linux directory, and moved
