arm64: Provide basic EL2 setup for FEAT_{LS64, LS64_V} usage at EL0/1
Instructions introduced by FEAT_{LS64, LS64_V} is controlled by
HCRX_EL2.{EnALS, EnASR}. Configure all of these to allow usage
at EL0/1.
This doesn't mean these instructions are always available in
EL0/1 if provided. The hypervisor still have the control at
runtime.
