core: arm32: fix saving vfp state

Prior to this patch TF-A in AArch32 didn't save the normal world VFP
data registers and thus always restored then as zeroes and causing
problems in normal world.

With this patch if running with TF-A in AArch32 save the VFP state using
the same logic as in AArch64. Since TF-A saves and restores CPACR_EL1 we
cannot tell if normal world currently is using VFP or not so we have to
assume that it is and always save the VFP data registers if they are
about to be changed.

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
