arm64: sysreg: add Set/Way sys encodings
Cache maintenance ops fall in the SYS instruction class, and KVM needs to handle them. So as to keep all SYS encodings in one place, this patch adds them to sysreg.h. The encodings were taken from ARM DDI 0487A.k_iss10775, Table C5-2. To make it clear that these are instructions rather than registers, and to allow us to change the way these are handled in future, a new sys_insn() alias for sys_reg() is added and used for these new definitions.
