[Why] When HUBP is power gated, the SW state can get out of sync with the hardware state causing cursor to not be programmed correctly. [How] Similar to DPP, add a HUBP reset function which is called wherever HUBP is initialized or powergated. This function will clear the cursor position and attribute cache allowing for proper programming when the HUBP is brought back up.
