This is a port of Linux driver for SDHC host controller hardware
found on Freescale's MX2 and MX3 processors. Uses new generic MMC
framework (CONFIG_GENERIC_MMC) and it looks like there are some
problems with a framework (at least on LE cpus). Some of these
problems are addressed in the following patches.

Here's a new framework (based roughly off the linux one) for managing
MMC controllers.  It handles all of the standard SD/MMC transactions,
leaving the host drivers to implement only what is necessary to
deal with their specific hardware.

This also hooks the infrastructure into the PowerPC board code
(similar to how the ethernet infrastructure now hooks in)

In order to consolidate more of the various MMC drivers around the
tree, we must first have a common place to put them.
