From 5cb5d0c964d15c14471dfbf6e66587edb5346206 Mon Sep 17 00:00:00 2001
From: Rob Herring <robh@kernel.org>

Subject: mailbox: Use device_get_match_data()

Use preferred device_get_match_data() instead of of_match_device() to
get the driver match data. With this, adjust the includes to explicitly
include the correct headers.
