[PATCH] ARM: OMAP: mmc MODULE_ALIAS, warnings

As with OHCI, the module name and device name differ, so to
coldplug a MODULE_ALIAS is needed.  Plus cope with a recent
API change, removing compile warnings (and oops if you use
the sysfs attributes).

Use DRIVER_NAME more, including as a MODULE_ALIAS so that coldplug
can work by scanning /sys/devices/platform and just modprobing.

Cope with some driver model changes that promote shared attribute
methods.
