The variable 'dw_mci_card_workqueue' is a global variable shared between
multiple instances of the dw_mmc host controller. Due to this, data
corruption has been noticed when multiple instances of dw_mmc controllers
are actively reading/writing the media. Fix this by adding a instance
of 'struct workqueue_struct' for each host instance and removing the
global 'dw_mci_card_workqueue' instance.

This driver is broken since 2.6.31 when the traditional i.MX1
support was removed.
In theory the i.MX1 mmc controller can be supported by the mxcmmc
driver which basically is the same hardware. However, the i.MX1
controller has severe bugs which made several workarounds necessary which
resulted in a different driver structure. At that time it seemed easier
to write a second driver to support hardware without bugs.
As noone cared for the i.MX1 driver for a long time and it does
not compile, remove it.

Commit c79396c191 ("mmc: sdhci: prevent card detection activity
for non-removable cards") disables card detection where the cards
are marked as non-removable.
This makes sense, but the implementation detail of calling
mmc_card_is_removable() causes some problems, because
mmc_card_is_removable() is overloaded with CONFIG_MMC_UNSAFE_RESUME
semantics.
In the OLPC XO case, we need CONFIG_MMC_UNSAFE_RESUME because our root
filesystem is stored on SD, but we also have external SD card slots
where we want automatic card detection.
Refine the check to only apply to hosts marked as MMC_CAP_NONREMOVABLE,
which is defined to mean that the card is *really* nonremovable. This
could be revisited in future if we find a way to improve
CONFIG_MMC_UNSAFE_RESUME semantics.

These are all specific to some driver. They are typically the platform
side of a change in the drivers directory, such as adding a new driver
or extending the interface to the platform. In cases where there is no
maintainer for the driver, or the maintainer prefers to have the
platform changes in the same branch as the driver changes, the patches
to the drivers are included as well.
A much smaller set of driver updates that depend on other branches
getting merged first will be sent later.
The new export of tegra_chip_uid conflicts with other changes in fuse.c.
In rtc-sa1100.c, the global removal of IRQF_DISABLED conflicts with
the cleanup of the interrupt handling of that driver.
