ARM: 6785/1: mmci: separate out ST Micro register defines

The mmci.h header contained a few registers not clearly marked
as ST Micro only, rectify this and remove the HWFC magic in the
process. The idea is to make the mmci.h header file more ordered
so other vendors with PL180 derivates can see where to put in
their custom register defines.

Includes portions of an earlier patch from Sebastian Rasmussen.

ARM: 6858/1: mmci: force negative edge on clock bypass for ux500

This fixes a regression on high clock speeds with the MMCI on
ux500. We need to make sure we derive the passthru clock on the
falling edge of the incoming clock if it shall work at high
frequencies, and on the ux500's there is a special bit for this.

mmc: remove redundant irq disabling

There is no need to disable irq's when using the sg_copy_*_buffer()
functions because those functions do that already. There are also
no races for the mm_queue struct here that would require the irq's
to be disabled before calling sg_copy_*_buffer().

mmc: sdhci: change CONFIG of MMC_SDHCI_TEGRA from 'tristate' to 'bool'

This config option is used to decide whether tegra sdhci support
should be build into the sdhci-platform module.  So setting it 'm'
is nonsense, since we can't build part of an module as a module.
The effect for 'm' will probably be the same as for 'n'.

Introduce MMC_QUIRK_NONSTD_FUNC_IF to ignore the "SDIO Standard Function

mmc: quirks: wl1271 is MMC_QUIRK_DISABLE_CD

The wl12xx device supports disconnecting the pull-up resistor on
CD/DAT[3] (pin 1) of the card.

Tell SDIO core to disconnect that resistor during card init,
since we don't need it at that point (and anyway all
hosts shall provide pull-up resistors on all data lines DAT[3:0]
as described in section 6 of the SD physical specification).

As a result, this may save some power, but it's also generally healthy
since it prevents both ends from pulling up that pin, which
results in undesirable asymmetric physical bus.
