mmc: Add MMC_PROGRESS_*
This is my second attempt to make this enum generally available.
The first attempt added MMCIF_PROGRESS_* to include/linux/mmc/sh_mmcif.h.
However this is not sufficiently generic as the enum will be
used by SDHI boot code.

mmc: sh_mmcif: Convert to __raw_xxx() I/O accessors.
When using the I/O accessors in raw mode from the boot stubs we don't
want to bother with any of the complexity associated with readl/writel
and friends. Furthermore, utilization within the context of the host
driver itself is all performed on an ioremapped window, so using the
__raw variants there doesn't pose any problem either.
If and when barriers need to be added in the future, these will need to
be explicitly written out, but this is so far not a concern for any of
the affected CPUs in question.
This fixes up the link error introduced by the ARM tree via its barrier
refactoring:
arch/arm/boot/compressed/mmcif-sh7372.o: In function `mmcif_loader':
mmcif-sh7372.c:(.text+0x9e8): undefined reference to `outer_cache

mmc, sh: Remove sh_mmcif_boot_slurp()
As the only caller of sh_mmcif_boot_do_read() is
sh_mmcif_boot_slurp() the configuration portion of
sh_mmcif_boot_slurp() can be merged into sh_mmcif_boot_do_read().
Once this is done sh_mmcif_boot_slurp() is only a call
to sh_mmcif_boot_do_read() with platform specific information -
the offset that images are stored on MMC. So make the
sh_mmcif_boot_do_read() call directly from platform code
and remove sh_mmcif_boot_slurp() altogether.

This resolves a regression that I introduced in
"mmc, sh: Move constants to sh_mmcif.h". Having
examined the manual and tested the code on an AP4EVB board
it seems that the correct sequence is.
1) Write 1 to bit 31 and zeros to all other bits
2) Write zero to all bits

mmc: sh_mmcif: add DMA support
The MMCIF controller on sh-mobile platforms can use the DMA controller for data
transfers. Interface to the SH dmaengine driver to enable DMA. We also have to
lower the maximum number of segments to match with the number od DMA
descriptors on SuperH, this doesn't significantly affect driver's PIO
performance.

mmc, sh: Move constants to sh_mmcif.h
This moves some constants from sh_mmcif.c to sh_mmcif.h
so that they can be used in sh_mmcif_boot_init().
It also alters the definition of SOFT_RST_OFF from (0 << 31) to
~SOFT_RST_ON (= ~(1 << 31)). The former seems bogus. The latter is
consistent with the code in sh_mmcif_boot_init().

mmc: sh_mmcif: Convert extern inline to static inline.
Presently the extern inline case results in a compiler warning on ARM due
to the memory barrier definition used in the I/O routines. These
ultimately all want to be static inline anyways, so just convert them all
in place.

mmc: Allow the platform to specify the sh_mmcif get_cd handler
In some platforms (e.g. AP4EVB) the card detect pin of a slot is not
directly connected to the sh_mmcif controller, so that polling needs
to be used. To overcome the overhead induced by querying the controller
on each poll cycle, card detection can be handled in the platform code
more efficiently.
This patch exposes a get_cd hook for that purpose.
