Add a V4L2 mem-to-mem driver for the Vivante DW100 Dewarp Processor IP
core found on i.MX8MP SoC.
The processor core applies a programmable geometrical transformation on
input images to correct distorsion introduced by lenses.
The transformation function is exposed as a grid map with 16x16 pixel
macroblocks indexed using X, Y vertex coordinates.
The dewarping map can be set from application through a dedicated v4l2
control. If not set or invalid, the driver computes an identity map
prior to starting the processing engine.
The driver supports scaling, cropping and pixel format conversion.
