Currently it's impossible to get CPU's microcode revision from Xen after
late loading without looking into Xen logs which is not always convenient.
Add an option to xen-ucode tool to print the currently loaded ucode
revision.

Sergey Dyasli (3):
  tools/xenctrl: add xc_get_cpu_version()
  x86/platform: introduce XENPF_get_ucode_revision
  tools/xen-ucode: print information about currently loaded ucode
