To clean things up and simplify move the definitions of the SCTLR_EL2 flags from kvm_arm.h to sysreg.h, rename any SCTLR_EL1 or SCTLR_EL2 flags that are common to both registers to be SCTLR_ELx, with 'x' indicating a common flag, and fixup all files to include the proper header or to use the new macro names.
