powerpc/ps3: Replace the flip_ctl logic in ps3av and ps3fb by a mutex
Introduce ps3_gpu_mutex to synchronizes GPU-related operations, like: - invoking the L1GPU_CONTEXT_ATTRIBUTE_FB_BLIT command using the lv1_gpu_context_attribute() hypervisor call, - handling the PS3AV_CID_AVB_PARAM packet in the PS3 A/V Settings driver.
