Add one flag to indicate the GPIO CD/WP is enabled or not
on imx platforms, and reuse the writel/readl as the general
APIs for imx SOCs.

SDHCI driver for Tegra. This driver plugs in as a new variant of
sdhci-pltfm, using the platform data structure passed in to specify the
GPIOs to use for card detect, write protect and card power enablement.

Original driver (of which only the header file is left):

This driver adds basic support for the esdhc-core found on e.g.
imx35/51, as a platform driver.

We need to carry some information per host, e.g. the clock. Add a
structure for it and initialize it in the generic part. Also improve
the check for a parent.

There's nothing special, just SoC-specific ops and quirks.

Sometimes want to place SoC-specific parts alongside with the generic
driver, and to do so, we have to switch the driver over to the module
device table matching.

Note that drivers/mmc/host/sdhci-pltfm.h is so far empty, but it'll hold
SoC-specific driver data handlers soon.
