SPI_IMX_VER_0_0 covers i.mx21 and i.mx27. It makes more sense to
use mx21 rather than mx27 to name SPI_IMX_VER_0_0 function and
macro, since i.mx21 comes out ealier than i.mx27.

spi_imx_devtype_data has already been driver private data. There is
really no need to make a copy in spi_imx_data. Instead, a reference
pointer works perfectly fine.

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
