ARM: mx3: dynamically allocate "ipu-core" devices
... together with the related devices "mx3_camera" and "mx3_sdc_fb". "mx3_camera" doesn't fit the scheme of the other devices that just are allocated and registered in a single function because it needs additional care to get some dmaable memory. So currently imx31_alloc_mx3_camera duplicates most of imx_add_platform_device_dmamask, but I'm not sure it's worth to split the latter to be able to reuse more code. This gets rid of mach-mx3/devices.[ch] and so several files need to be adapted not to #include devices.h anymore.
