plat-sam: matrix: update code to be reuseable for sama7g5

Besides sama5d2, sama7g5 also has the matrix. Following changes are done
to make the code reuseable for supporting sama7g5:
- move definition of "peri_security_array[]" from matrix.c to main.c
- replace "matrix32_base()" and "matrix64_base()" with "matrix_base()"
- update code according to the above changes

plat-sam: matrix: add matrix_dt_get_id() to parse matrix id from dt

Rather than using hardcoded values for matrix identifier in drivers
themselves, (which might change in future hardware SoC), add
matrix_dt_get_id() function which allows to retrieve the ID based on a
devite-tree node reg property. This property contains the address of the
peripheral and thus can be used to match the address with an identifier.
This is also useful for peripheral which have multiple instances and thus
id is not the same for all of them.

Add SPDX license identifiers

Adds one SPDX-License-Identifier line [1] to each source files that
contains license text.

Generated by [2]:
spdxify.py --add-spdx optee_os/

The scancode tool [3] was used to double check the license matching
code in the Python script. All the licenses detected by scancode are
either detected by spdxify.py, or have no SPDX identifier, or are false
matches.
