Although both the U300 and Ux500 use ST variants, the HWFCEN bits are at
different positions, so use the variant_data to store the information.

Add a variant_data structure to handle the differences between the
various variants of this peripheral. Add a first quirk for a default
MCICLOCK value, required on the Ux500 variant where the enable bit needs
to be always set, since it controls access to some registers.

The mmci driver's SG list iteration logic assumes that each SG entry
spans only one page, and only maps and flushes one page of the sg. This
is not a valid assumption. Fix it by converting the driver to the
sg_miter API, which correctly handles sgs which span multiple pages.

This adds support for an 8bit wide bus to the card (data lines
MCIDAT0 through 7 exist) on the ST Micro version and alters the
U300 platform to support this. Also add some ST_ prefix to the
ST-specific registers.

This enables the use of a regulator to power the MMCI/PL180
PrimeCell. The OCR mask is calculated and voltage is set using
the new MMC core functions for discovering voltage ranges
in regulators. The platform translate_vdd function which basically
controls the 4 lines out of the PL180 is disabled if you use a
regulator instead.

This moves the mmci platform data definition struct away from
arch/arm/include/asm/mach/mmc.h into the more proper place among
the other primecells in include/linux/amba/mmci.h and at the same
time renames it to "mmci.h", and also the struct in this file
confusingly named mmc_platform_data has been renamed
mmci_platform_data for clarity.

Use gpiolib where available (and when valid GPIOs are provided) for
write protect/card detect status reporting. We fall back to the old
'status' method where gpiolib support is not available.

This patch adds support for the ST Microelectronics version of
the PL180 PrimeCell. They use designer ID 0x80 and have a few
alterations/bugfixes related to open drain and HW flow control.
They also add some SDIO registers, I am unsure if these are
in ST HW only or if this is things also added in later ARM
revisions, but they are included in the mmci.h file for
completeness.

Clean up the drivers/mmc directory by moving card and host drivers
