SPMD: Adds partially supported EL2 registers.
This patch adds EL2 registers that are supported up to ARMv8.6. ARM_ARCH_MINOR has to specified to enable save/restore routine. Note: Following registers are still not covered in save/restore. * AMEVCNTVOFF0<n>_EL2 * AMEVCNTVOFF1<n>_EL2 * ICH_AP0R<n>_EL2 * ICH_AP1R<n>_EL2 * ICH_LR<n>_EL2 Change-Id: I4813f3243e56e21cb297b31ef549a4b38d4876e1 Signed-off-by: Max Shvetsov <maksims.svecovs@arm.com>
