This patch resurrects an old never-finished driver for Toshiba PCI SD
controllers found in some older Toshiba laptops (such as Portege R100):

02:0d.0 System peripheral [0880]: Toshiba America Info Systems SD TypA Controller [1179:0805] (rev 05)

The code is fixed, cleaned up and successfully tested with SD, SDHC, SDXC and
MMC cards on Portege R100. (MMC cards don't even work in Windows!)
SDIO probably does not work (don't have any SDIO card).

The hardware is slow (around 2 MB/s - same in Windows) because it does not
support bus mastering (busmaster enable bit cannot be set in PCI control reg).
Also the card clock is limited to 16MHz (33MHz PCI clock divided by 2).

On Qualcomm APQ8064 SOCs, SD card controller has an additional glue
called DML (Data Mover Local/Lite) to assist dma transfers.
This hardware needs to be setup before any dma transfer is requested.
DML itself is not a DMA engine, its just a gule between the SD card
controller and dma controller.

Most of this code has been ported from qualcomm's 3.4 kernel.

This patch adds the code necessary to intialize the hardware and setup
before doing any dma transfers.

This driver is broken since 2.6.31 when the traditional i.MX1
support was removed.

In theory the i.MX1 mmc controller can be supported by the mxcmmc
driver which basically is the same hardware. However, the i.MX1
controller has severe bugs which made several workarounds necessary which
resulted in a different driver structure. At that time it seemed easier
to write a second driver to support hardware without bugs.

As noone cared for the i.MX1 driver for a long time and it does
not compile, remove it.

There are a couple of problems left from the sdhci pltfm and OF
consolidation changes.

* When building more than one sdhci-pltfm based drivers in the same
  image, linker will give multiple definition error on the sdhci-pltfm
  helper functions.  For example right now, building sdhci-of-esdhc
  and sdhci-of-hlwd together is a valid combination from Kconfig view.

* With the current build method, there is error with building the
  drivers as module, but module installation fails with modprobe.

The patch fixes above problems by changing sdhci-pltfm into a module.
To avoid EXPORT_SYMBOL on so many big endian IO accessors, it moves
these accessors into sdhci-pltfm.h as the 'static inline' functions.
As a result, sdhci.h needs to be included in sdhci-pltfm.h, and in
turn can be removed from individual drivers which already include
sdhci-pltfm.h.

The patch turns the sdhci-of-core common stuff into helper functions

As a result, sdhci-of-core.c and sdhci-of.h can be eliminated with
those common things merged into sdhci-pltfm.c and sdhci-pltfm.h
respectively.
