gpu: ipu-v3: pre: add dynamic buffer layout reconfiguration
imx-drm doesn't mandate a modeset when the framebuffer modifier changes,
but currently the tile prefetch and resolve (TPR) configuration of the
PRE is only set up on the initial modeset.
As the TPR configuration is double buffered, same as all the other PRE
states, we can support dynamic reconfiguration of the buffer layout from
one frame to another. As switching between (super-)tiled and linear
prefetch needs to touch the CTRL register make sure to do the
reconfiguration inside the safe window.
