Update MM_SP_MEMORY_ATTRIBUTES_GET_AARCH64 interface
correspondant to FF-A v1.3 memory management protocol's
FFA_MEM_PERM_GET interface [0].

This adds one input/output parameter with page_count
to set search range and get the range having same permssion from
base_va.

This change is backward compatible.

feat(spm): separate StMM SP specifics to add support for a S-EL0 SP

This patch separates the code from SPM_MM to get xlat table context and
move it to a common location. In addition, only APIs required from both
SPM_MM and FF-A EL3 SPMC are moved to the common location.

This allows understanding better what is required to support a S-EL0 SP
instead of trying to retrofit what already exists.

refactor(spm-mm): reorganize secure partition manager shim code

In preparation for adding the support for SEL0 SP in EL3 SPMC,
restructure the existing SPM_MM shim code in a way that allows reuse
of the code for both SPM_MM interface and FF-A EL3 SPMC interface. The
code for changing exception levels is identical for both.

With this restructuring of the code, the shim exception code is moved to
the common sub-directory.

build: always prefix section names with `.`

Some of our specialized sections are not prefixed with the conventional
period. The compiler uses input section names to derive certain other
section names (e.g. `.rela.text`, `.relacpu_ops`), and these can be
difficult to select in linker scripts when there is a lack of a
delimiter.

This change introduces the period prefix to all specialized section
names.

BREAKING-CHANGE: All input and output linker section names have been
prefixed with the period character, e.g. `cpu_ops` -> `.cpu_ops`.

refactor(spm_mm): reorganize secure partition manager code

In preparation for adding the EL3 SPMC configuration as defined in
the FF-A specification, restructure the existing SPM_MM code.

With this restructuring of the code, the 'spm_mm' directory is
renamed as 'spm' and the code inside has been split into two
sub-directories named 'common' and 'spm_mm'. The code in 'spm_mm'
directory contains the code that implements the MM interface.
In subsequent patches, the 'spmc' directory will be introduced
under the 'spm' directory providing the code that implements
the 'FF-A' interface.

Currently the common functionality for S-EL1 partitions is
limited to assembler functions to enter and exit an SP
synchronously.
