spi/atmel: Fix pointer to int conversion warnings on 64 bit builds
On 64 bit systems integers are generally still 32 bit but long values and
pointers are usually 64 bit. GCC warns when casting a 64 bit pointer into
a 32 bit integer so cast to a long instead in order to avoid warnings.

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.

atmel/spi: fix missing probe
Commit 940ab889 "drivercore: Add helper macro for platform_driver boilerplate"
converted this driver to use module_platform_driver, but due to the use
of platform_driver_probe(), this resulted in the call to atmel_spi_probe being
lost. Place the call to this function into the driver structure.
fix section missmatch
atmel_spi_probe is marked __init where it's supposed to be __devinit
atmel_spi_remove is marked __exit where it's supposed to be __devexit

drivercore: Add helper macro for platform_driver boilerplate
For simple modules that contain a single platform_driver without any
additional setup code then ends up being a block of duplicated
boilerplate. This patch adds a new macro, module_platform_driver(),
which replaces the module_init()/module_exit() registrations with
template functions.

spi: reorganize drivers
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
