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 common stuff in sdhci-pltfm.c into functions, and
add device drivers their own .probe and .remove which in turn call
into the common functions, so that those sdhci-pltfm device drivers
register itself and keep all device specific things away from common
sdhci-pltfm file.

Enable fast bcm4329 WIFI suspend/resume on Tegra2 board.

This patch allows the mach-tegra support to tell the tegra MMC host
controller to NOT turn off power for the MMC controller the WIFI part
lives behind.  Thus bcm4329 firmware doesn't need to be reloaded.

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):
