OMAP: McBSP: Convert McBSP to platform device model
Implement McBSP as platform device and add support for
registering through platform device layer using resource
structures.
Later in this patch series, OMAP2+ McBSP driver would be modified to
use hwmod framework after populating the omap2+ hwmod database.
