Paul, Kevin, to me it looks like a duplication that all devices will
have to:
oh = omap_hwmod_lookup("my_hwmod_name");
omap_device_build("my_device_name", bus_id, oh, pdata, sizeof(*pdata));
could the omap_hwmod_lookup() part be moved to omap_device_build ? Or
maybe create a omap_hwmod_lookup_and_build(oh_name, dev_name, bus_id,
pdata, sizeof(*pdata)) ??

use sizeof(*pdata), if we change the name of that structure (very
unlikely, but still) it'll avoid unwanted compile breakage.

I think this is also a duplication, it's gonna on all hwmod device
registration, no ?
