Vasiliy Kulikov abebbb4680 arm: dma: check clk_get() result
clk_get() may return ERR_PTR(), if so propagate return code as
imx_dma_init() return code.

Sascha Hauer 8bffb77e19 ARM i.MX DMA: return gracefully on different socs
Code called from an initcall can be maybe called for
machines it's not intended for. So check for valid
machines and return gracefully if an incompatible machine
is found.

Uwe Kleine-König 9f72ffedc8 ARM: imx: new Kconfig symbol and feature test macro for DMA on mx1 and mx2
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.
