Steve Longerbeam 58e366eb86 gpu: ipu-v3: Fix IRT usage 
There can be multiple IC tasks using the IRT, so the IRT needs
a separate use counter. Create a private ipu_irt_enable() to
enable the IRT module when any IC task requires rotation, and
ipu_irt_disable() when a task no longer needs the IRT.

The value for downsizing 8:1 is marked as reserved in the technical reference
manual and the documentation states downsizing capability up to 4:1 only.
