This will simplify the MMC low-level init, and make it more flexible to add support for a newer MMC controller in the following patches. The patch rearranges platform data and gets rid of slot vs controller confusion in the old data structures. Also fix device id numbering in the clock code. Some code snippets are based on an earlier patch by Russell King <linux@arm.linux.org.uk>. Cc: Pierre Ossman <drzeus-mmc@drzeus.cx> Signed-off-by: Tony Lindgren <tony@atomide.com>
