This should be used instead of hard coding the corresponding platforms.
The feature test macro is needed to support different SOCs in a single
kernel image. While at it rename dma-mx1-mx2 to dma-v1 as mx25 doesn't
use it and so the mx2 part is wrong and move the header to
arch/arm/mach-imx.

This fixes a regression of
7d58289 (mx1: prefix SOC specific defines with MX1_ and deprecate old names)

This is useful for audio where we do not want to setup a new scatterlist
after playing 4GB of audio data. This would cause skips in the playback.

This one updates DMA support on MX2 which got broken in:
[ARM] Hide ISA DMA API when ISA_DMA_API is unset

When ISA_DMA_API is unset, we're not implementing the ISA DMA API,
so there's no point in publishing the prototypes via asm/dma.h, nor
including the machine dependent parts of that API.
This allows us to remove a lot of mach/dma.h files which don't contain
any useful code. Unfortunately though, some platforms put their own
private non-ISA definitions into mach/dma.h, so we leave these behind
and fix the appropriate #include statments.

This patch adds DMA support for Freescale i.MX27 SoCs. It is derived
from the i.MX1 port and should (though currently untested) still be
working for the i.MX1.
