gpu: ipu-v3: pre: implement workaround for ERR009624 The PRE has a bug where a software write to the CTRL register can block the setting of the ENABLE bit by the hardware in auto repeat mode. When this happens the PRE will fail to handle new jobs. To work around this software must not write to CTRL register when the PRE store engine is inside the unsafe window, where a hardware update to the ENABLE bit may happen.
