[PATCH] ARC: Remove unneeded Kconfig entry NO_DMA

[Paul Bolle]

Architectures only need a Kconfig entry for NO_DMA if it is possible
that its value will be 'y'. For arc its value will always be 'n', making
it pointless. Remove it.

Tested by playing with arch/arc/configs/tb10x_defconfig. The only
difference this change should make, is that the line reading
    # CONFIG_NO_DMA is not set

is dropped from the .config file after "make oldconfig". That should
have no impact whatsoever on the build.
