  Enable CONFIG_SCOM_DEBUGFS for ppc64el kernels

Bug description:
  [Impact]
  Please enable CONFIG_SCOM_DEBUGFS for ppc64el kernels, this creates some new files in debugfs that allow userspace (root only) to access the P7/P8 chip internal XSCOM bus, which is needed for  various debug/diag/mfg tools. There should be no runtime impact on performance or stability by just enabling that option.

  [Test Case]
   ls /sys/kernel/debug/powerpc/scom/*

  [Fix]
  Enable CONFIG_SCOM_DEBUGFS for powerpc/powerpc64-smp and ppc64el/generic arch/flavors.
