CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, and __devexit
from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Since v3.2 we have nice macro to define the platform driver's init and exit
calls. This patch simplifies the dw_mmc platform driver by using that macro.

The of_device_id match data is now marked as const and
must not be modified. This changes the dw_mmc to mark
all pointers passing the dw_mci_drv_data or dw_mci_dma_ops
structures as const, and also marks the static definitions
as const.

800d78bf ("mmc: dw_mmc: add support for implementation specific
callbacks") -- merged in v3.7-rc1 -- introduced multiple NULL pointer
dereferences when the default dw_mci_pltfm_probe() is used, as it sets
host->drv_data to NULL, and that's only checked against NULL in 1 out of
the 7 cases where it is dereferenced.

The core dw-mshc controller driver can let platform specific
implementations of the dw-mshc controller to control the hardware
as required by such implementations. This is acheived by invoking
implementation specific (optional) callbacks. Define the list of
callbacks supported the add invocation points for the same.

Platform implementations of dw-mshc controller may choose to extend the
features of the standard dw-mshc controller such as adding additional
clocking options or modifying the bus interface. Support for such
implementation specific extensions can be incorporated into dw_mmc-pltfm,
but including multiple such platform specific implementations would
convolute the existing dw_mmc-pltfm code.

Instead, it would be better to create implementation specific platform
drivers to support implementation specific features. Such platforms
drivers can reuse the existing infrastructure in dw_mmc-pltfm for
resource identification and controller registration and provide support
for implementation specific features. So, allow the infrastructure in
dw_mmc-pltfm to be reused by other implementation specific platform
drivers.

The 'struct dw_mci' maintains a copy of the pdev->dev instance instead of
maintaining a reference to that 'struct device' instance. Any resource
allocated using the device resource management kernel API with the instance
of 'struct device' in 'struct dw_mci' is then incorrect. Fix this by
converting the copy of 'struct device' in 'struct dw_mci' to a reference.

Fixed the below message.

WARNING: drivers/mmc/host/built-in.o(.text+0x5ee8): Section mismatch in reference from the function dw_mci_probe() to the function .init.text:dw_mci_init_slot()
The function dw_mci_probe() references
the function __init dw_mci_init_slot().
This is often because dw_mci_probe lacks a __init

Support of PCI mode for the dw_mmc driver. This Patch adds the
support for the scenario where the Synopsys Designware IP
is present on the PCI bus. The patch adds the minimal modifications
necessary for the driver to work on PCI platform. Also added separate
files for PCI and PLATFORM modes of operation.
