Later patch will come to use it in davinci_nand.c and get
rid of a define there. In DM355, the base is different, so
better to apply this patch before adding support for DM355
nand chip.

This shrinks the object size of davinci_mmc by about a quarter,
ripping out stuff that was issuing all kinds of commands behind
the back of the MMC core (evidently for card detect purposes).

That's stuff that needs to be ripped out before this driver can go
into mainline, obviously; good to remove it ASAP.

This has one immediate positive effect:  cards which previously could
not be enumerated on a dm355evm can now enumerate!  (After disabling
DMA, for now.)  Which in turn let me boot a rootfs from an SD card ...

There still seems to be state kept around after card removal, which
prevents a second card from enumerating after removing the first one.
Also, the MMC core failed when enumerating an MMC card; odd!

(Plus fix two broken debug messages:  voltages use a bitmask, and
newlines don't belong in the *middle* of messages.)

Cleanup the way the memory regions are intialised and removes the hard-coded
offsets used for EMAC internal modules (MDIO, Control RAM, EMAC wrapper)
i.e the assumption that all modules are at fixed offset from the EMAC "base".

Also removes the hard coded values for the RAM size, number of transmit and
receive buffer descriptors, instead gets the info from the driver structure.

Update DM6466 EVM to support the new MMC board config data.

This provides a miniature I2C driver in the board-dm644x-evm.c
file ... unusual, but it does make it easier to pass the key
information easily to the MMC driver.

There's no attempt to use the gpio_to_irq(GPIO(7)) signals that
are issued when the various card detect signals change, or when
the IR remote sends a command.

Inital support for new MMC init logic, where boards can say how
to initialize what, and also provide functions to sense card
detect and writeprotect switches.  This also removes some
static driver configuration forcing it to always use 4-bit
parallel data channels; boards can now override that.

This patch stubs in support for the two EVM boards with MMC/SD
support, equivalent to current behavior ... later patches will
update these.  SFFSDR presumably needs something too.

Note that this doesn't currently handle card detect IRQs.
