Debug Linux eMMC driver

It's unclear whether this is a major bug or not. The filesystem is able to mount off an SD card, albeit with errors. It's possible my card is faulty as opposed to the driver. I need to look into this further.

(It is worth noting you need to do a dance unplugging and replugging in the card, though.)

High priority bug, I will look into the proper state machine reset sequence tonight. Reasoning behind this is that SDHOST is fairly crucial and the card pull out/in hacks aren't really a proper solution. I will get an environment set up and test this all out. I think being able to get Linux to mount off a real SD card without weird hacks is one of the major, if not the first milestone we should be working on.

@bobbybee Can you provide the zImage you've been using and/or a copy of your Linux kernel sources as well as your Kconfig. Don't feel like configuring/building my own.
