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.
