From: Vivek Kumar Chaubey <vivekkumar.chaubey@citrix.com>

Allow setting system enclosure asset tag for HVM guest. Guest OS can
check and perform desired operation like support installation.
Also added documentation of '~/bios-string/*' xenstore keys into
docs/misc/xenstore-paths.markdown

Changes since v2(Review changes):
  * Remove style changes to existing lines
  * Add documentation for xenstore keys '~/bios-strings/*' to
docs/misc/xenstore-paths.markdown
