For the planar but U/V-packed formats NV12 and NV16, 8 pixel width
alignment is good enough to fulfill the 8 byte stride requirement.
If we allow the input 8-pixel DMA bursts to overshoot the end of the
line, the only input alignment restrictions are dictated by the pixel
format and 8-byte aligned line start address.
Since different tile sizes are allowed, the output tile with / height
alignment doesn't need to be multiplied by number of columns / rows.

Slightly modifying resize coefficients per-tile allows to completely
hide the seams between tiles and to sample the correct input pixels at
the bottom and right edges of the image.
Tiling requires a bilinear interpolator reset at each tile start, which
causes the image to be slightly shifted if the starting pixel should not
have been sampled from an integer pixel position in the source image
according to the full image resizing ratio. To work around this
hardware limitation, calculate per-tile resizing coefficients that make
sure that the correct input pixels are sampled at the tile end.

Prevent possible race by parallel threads between ipu_image_convert_run()
and ipu_image_convert_unprepare(). This involves setting ctx->aborting
to true unconditionally so that no new job runs can be queued during
unprepare, and holding the ctx->aborting flag until the context is freed.
Note that the "normal" ipu_image_convert_abort() case (e.g. not during
context unprepare) should clear the ctx->aborting flag after aborting
any active run and clearing the context's pending queue. This is because
it should be possible to continue to use the conversion context and queue
more runs after an abort.
