Migrates the fsl-(e)spi driver to use the generic master queuing.
Avoids the "master is unqueued, this is deprecated" warning.

Sort all the include headers alphabetically for the freescale
spi drivers. If the inlcude headers sorted out of order, maybe
the best logical choice is to append new ones after the exist
ones, while this may create a lot of potential for duplicates
and conflicts for each diffenent changes will add new headers
in the same location.

ret is unused when CONFIG_FSL_SOC defined,
so return ret instead of -ENOMEM when the
kzalloc fails to avoid it.

devm_kzalloc
In current code, master->cleanup and master->setup are not set in the same
function. This makes it hard to read and not good for code maintain.
One example is in fsl-spi.c, master->cleanup is overrided in mpc8xxx_spi_probe()
which leads to a memory leak.
This patch removes mpc8xxx_spi_cleanup() and converts fsl_espi_setup to use
devm_kzalloc so we don't need to take care of freeing memory.

of_mpc8xxx_spi_probe() allocates memory for pinfo but the memory is not freed
anywhere. of_mpc8xxx_spi_probe() is called in .probe() and pinfo should be
freed in .remove(), so convert kzalloc to devm_kzalloc to fix the memory leak.

Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly.

environment
This makes the spi-fsl-spi driver usable in CPU mode outside of an FSL_SOC and
even an powerpc environment by moving CPM mode functionality to a separate file
that is only compiled and linked in an FSL_SOC environment and adding some
ifdefs to hide types and functions or provide alternatives.
For devicetree probing a "clock-frequency" property is used for clock frequency
instead of calls to FSL_SOC-specific functions.

CONFIG_HOTPLUG is going away as an option. As result the __dev*
markings will be going away.
Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst,
and __devexit.
Bill Pemberton has done most of the legwork on this series. I've used
his script to purge the attributes from the drivers/gpio tree.

The SPI device tree support code isn't shared by any other subsystem. It can
be moved into the core drivers/spi directory and the exported symbol can be
removed.

Sort the SPI makefile and enforce the naming convention spi_*.c for
spi drivers.
This change also rolls the contents of atmel_spi.h into the .c file
since there is only one user of that particular include file.
v2: - Use 'spi-' prefix instead of 'spi_' to match what seems to be
be the predominant pattern for subsystem prefixes.
- Clean up filenames in Kconfig and header comment blocks
