These bits are actually RAZ/WI. I know that doesn't amount to much right
now, but eventually getting a mask of RAZ/WI bits for registers would be
helpful for KVM sysreg emulation.

Our standard scheme for naming the constants for bitfields in system
registers includes _ELx in the name but not the SYS_, update the
constants for OSL[AS]R_EL1 to follow this convention.
