Remove 'All rights reserved' from Linaro files

The text 'All rights reserved' is useless [1]. The Free Software
Foundation's REUSE Initiative best practices document [2] does not
contain these words. Therefore, we can safely remove the text from the
files that are owned by Linaro.

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.

Add plat-vexpress

* Initial support for Versatile Express of FVP with ARM Trusted
Firmware (ATF below)

* Use entry vector for entering TEE

Align interface between TEE and secure monitor with the interface
between OPTEED in ATF and TEE.

Uses an ATF compatible entry vector for entering TEE from internal
secure monitor.

Internal secure monitor saves entry reason to be able to tell when
switching back to nonsecure world if r0-r3 should be preserved (FIQ case)
or returned as is (normal call case).

* Many small fixes of generic problems that could affect other platforms
too.

* Disable unaligned data accesses by adding compiler flag
-mno-unaligned-access

* Adds support for Versatile Express of QEMU with 8 MiB of secure DRAM
