In case of error, the function platform_device_register_full()
returns ERR_PTR() and never returns NULL. The NULL test in the
return value check should be replaced with IS_ERR().

The spi-pxa2xx-pci glue driver had to implement pxa_ssp_request()/free() in
order to support the spi-pxa2xx platform driver. Since the ACPI enabled
platforms can use the same platform driver we would need to implement
pxa_ssp_request()/free() in some central place that can be shared by the
ACPI and PCI glue code.

Instead of doing that we can make pxa_ssp_request()/free() to be available
only when CONFIG_ARCH_PXA is set. On other arches these are being stubbed
out in preference to passing the ssp_device from the platform data
directly.

We also change the SPI bus number to be taken from ssp->port_id instead of
platform device id. This way the supporting code that passes the ssp can
decide the number (or it can set it to the same as pdev->id).

Instead of open-coding all the error management in the driver we can take
advantage of the pcim_* interfaces that release the resources automatically.

We also use platform_device_register_full() to register the platform device
because it allows us to create and register the platform device at one go,
simplifying the error management.

This a preparatory step for getting rid of pxa_ssp_request()/free() which
we will do in the next patch.

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.

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.

Right now the platform device and its platform data is included in one big
struct which requires its custom ->release function. The problem with the
release function within the driver is that it might be called after the
driver was removed because someone was holding a reference to it and it
was not called right after platform_device_unregister(). So we also free
the platform device memory to which one might hold a reference.

This patch uses the normal pdev functions so this kind of race does not
occur.

Having conditional around the of_match_table and the of_node pointers
turns out to make driver code use ugly #ifdef blocks.  Drop the
conditionals and remove the #ifdef blocks from the affected drivers.

Also tidy up minor whitespace issues within the same hunks.

Sodaville's SPI controller is very much the same as in PXA25x. The
difference:
- The RX/TX FIFO is only 4 words deep instead of 16
- No DMA support
- The SPI controller offers a CS functionality
