Subject: [PATCH] pinctrl: intel: merrifield: Add missed header
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

On x86 builds the absense of <linux/io.h> makes static analyzer and compiler
unhappy which fails to build the driver.

Add header to the top of the module.
