msm: sde: Add dynamic OT support for rotator REGDMA
Dynamic OT is applied before rotator operation to control QoS.
Since REGDMA cannot access QoS registers directly, rotator
driver needs to wait for rotator idle before changing any
OT settings. Once new OT is applied, REGDMA can resume
queueing until OT changes again.
