Merge branch 'for-next/sysreg-hwcaps' into for-next/core

* for-next/sysreg-hwcaps:
  : Make use of sysreg helpers for hwcaps
  arm64/cpufeature: Use helper macros to specify hwcaps
  arm64/cpufeature: Always use symbolic name for feature value in hwcaps
  arm64/sysreg: Initial unsigned annotations for ID registers
  arm64/sysreg: Initial annotation of signed ID registers
  arm64/sysreg: Allow enumerations to be declared as signed or unsigned
