Log:
  loader: add aarch64 support for zstd
  
  We don't have NEON available in the boot loader, so we have to disable
  it. OpenZFS included ZSTD which used the wrong symbol to bring in neon
  support. Change to use the code that's been submitted upstream as a
  pull request to both.
  
  __ARM_NEON is the proper symbol, defined in ARM C Language Extensions
  Release 2.1 (https://developer.arm.com/documentation/ihi0053/d/). Some
  sources suggest __ARM_NEON__, but that's the obsolete spelling from
  prior versions of the standard.

  ZSTD Pull Request: https://github.com/facebook/zstd/pull/2356
