In order to support Mailbox links for the Amlogic GXBB SoC, add a generic
platform MHU driver based on arm_mhu.c.

This patchset follows a RFC thread along the GXBB SCPI support at :
http://lkml.kernel.org/r/1466503374-28841-1-git-send-email-narmstrong at baylibre.com
And specific MHU discussions at :
http://lkml.kernel.org/r/CABb+yY3HqJG2+GMWCWF9PomxobrwWGZ=TZe5NvXPcHMDdLhkcQ at mail.gmail.com

Changes since RFC v2 :
 - Rename to platform_mhu
 - Sync all link functions with arm_mhu

  mailbox: Add Platform Message-Handling-Unit variant driver
  dt-bindings: mailbox: Add Amlogic Meson MHU Bindings
