The spi core make sure that each transfer structure have the proper
setting for bits_per_word before calling low level transfer APIs.
Hence it is no more require to check again in low level driver for
this field whether this is set correct or not. Removing such code
from low level driver.
The txx9 change also removes a test for bits_per_word set to 0, and
forcing it to 8 in that case. This can also be removed now since
spi_setup() ensures spi->bits_per_word is not zero.
if (!spi->bits_per_word)
spi->bits_per_word = 8;

We are clipping down the presence of module.h, since it was
everywhere. If you really need it, you better call it out,
as per this changeset.

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
