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.

I slightly moved the OMAP4 dev_attr as discussed in my previous comment
to the right place.
The updated patch is below.
Thanks,
Benoit

OMAP: hwmod data: Add dev_attr and use in the host driver
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.
