SCR & switch data are read from card as big-endian words and should be
converted to CPU byte order.

Cards which are not compatible with SD 2.0 standard, may return response
for CMD8 command, but it will be invalid in terms of SD 2.0. We should
accept this case as admissible, just like Linux does.

Now that response is a uint, we can drop all the casts.

The mmc code defines the response as an array of chars. However, it
access the response bytes both as (i) an array of four uints (with
casts) and (ii) as individual chars. The former case is used more
often, including by the driver when it assigns the response.
The char-wise accesses are broken on little endian systems because they
assume that the bytes in the uints are in big endian byte order.
This patch fixes this by changing the response to be an array of four
uints and replacing the char-wise accesses with equivalent uint-wise
accesses.

The generic MMC core uses direct long long divisions, which do not build
with ARM EABI toolchains. Use lldiv() instead, which works everywhere.

find_mmc_device returns NULL if an invalid device number is specified.
Check for this to avoid dereferencing NULL pointers.

__attribute__ follows gcc's documented syntax and is generally more
common than __attribute. This change is only asthetic and should not
affect functionality.

The Blackfin SDH controller is still using the legacy framework, so update
the driver to use the renamed functions.

Clean up OMAP3 MMC code:
* Convert register access to struct & readx/writex style
* Replace hardcode values by macros
* Remove macro defined twice

These names are being taken over by the new MMC framework. Hopefuly
the PXA can be easily ported, and these functions will go away entirely.

This uses the new MMC framework

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)

MMC cards are not memory, so we stop treating them that way.

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