spi: Fix WARN when removing spi-fsl-spi module

If CPM mode is not used, the fsl_dummy_rx variable is never allocated.  When
the cleanup attempts to free it, the reference count is zero and a WARN is
generated.  The same CPM mode check used in the initialize is applied to the
free as well.

Tested on 2.6.33 with the previous spi_mpc8xxx driver.  The renamed
spi-fsl-spi driver looks to have the same problem.

spi/fsl_spi: fix CPM spi driver

This patch fixes the freescale spi driver for CPM. Without this
patch SPI on CPM failed because cpm_muram_alloc_fixed tries to
allocate muram in an preserved area. The error reported was:

mpc8xxx_spi f0011a80.spi: can't allocate spi parameter ram
mpc8xxx_spi: probe of f0011a80.spi failed with error -12

Now the driver uses of_iomap to get access to this area
similar to i2c driver driver in the i2c-cpm.c which has a
similar device tree node. This is tested on a MPC8247 with CPM2.

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
