[PATCH 2/3] mtd: m25p80: Initialize the addr_width field of spi_message

[Zhiqiang Hou <B48286-KZfg59tc24xl57MIdRCFDg@public.gmane.org>]

From: Hou Zhiqiang <B48286-KZfg59tc24xl57MIdRCFDg@public.gmane.org>

Add the addr_width information of spi_nor delivery to SPI controller.

For the Freescale eSPI controller, the address width is needed to do
the correct operations.
