aarch64: Remove support for CSRE
This patch removes support for the CSRE extension from aarch64
gas/objdump.
CSRE (FEAT_CSRE) is part of the Future Architecture Technologies program
and at this time Arm is withdrawing this particular feature.
The patch removes the system registers and the CSR PDEC instruction.
