Add a device attribute to hwmod data of omap2430, omap3, omap4.
Currently the device attribute holds information regarding dual volt MMC card
support by the controller which will be later passed to the host driver via
platform data.

Could you rename the struct omap_mmc_dev_attr to stick to the convention?
The dev_attr should be just above "static struct omap_hwmod". See the
OMAP4 example below.

If you do not have any dev_attr for that instance, do not add it here
and test for null pointer in your driver.
This comment applies for all instances in all OMAPs.

mm1 needs dev_attr, the OMAP4 diff should be:
