svn commit: r365304 - head/sys/arm64/include

Log:
  arm64: update the set of HWCAP definitions
  
  This is in sync with what is defined for Linux 5.8. Note that all bits
  in HWCAP are exhausted, and HWCAP2 has been added.
  
  This also revealed an error in some of the existing definitions. We are
  missing HWCAP_ASIMDHP, and as a result a portion of the HWCAP values are
  shifted right by one bit. This will be fixed in an upcoming change, but
  the values being added now are compatible with what Linux defines.
