ENGR00272541 IPUv3 IC: Split Downsizing overflow for size greater than 1024

For downscaling, it is possible that downscaler output is greater
than 1024. Added a function, calc_split_resize_coeffs, based upon
_calc_resize_coeffs to calculate resizing and downscaling coefficients.

In ipu_ic.c, checks for the range of *_resize_ratio are no longer needed.
 Non split cases will always have  *_resize_ratio of zero.

In ipu_device, additional checks are needed to check for an error from
ipu_calc_stripes_sizes if calc_split_resize_coeffs fails.

iMX6 VPU: Use a DMA allocation pool, instead of kernel default allocator

This resolves problems with allocating physical memory for DMA transfers.
By default, the kernel dma_alloc_coherent() method returns the first
available block that is big enough. This inevitably leads to fragmentation,
since the VPU requests blocks of very varying sizes (80k -- 5M), and
eventual failure to find a large enough block.

With this patch the VPU driver keeps a number of blocks cached.

The drawback of this patch is that DMA memory gets tied up inside the VPU
driver, and never freed. The size can be limited by the ARM_DMA_ZONE size
define in memory.h. There are also limits on the number and sizes of
blocks cached (and unused blocks beyond that are not cached but freed).
