The DaVinci NAND driver was including the mach-types.h header
file.
This prevented the DaVinci NAND driver from getting used
in a DSP only device. The linux port on c6x devices can make
use of the same driver and does not define a corresponding
header file.

This header file was required in the driver because earlier there was code
dependent on a machine_* check. This piece of code has now been factored out
and is in arch/arm/mach-davinci/aemif.c

Thus removing the header file is harmless
