Revert "drm/exynos: g2d: fix system and runtime pm integration" This reverts commit b05984e21a7e000bf5074ace00d7a574944b2c16. The change, i.e. merging the sleep and runpm operations, produces a deadlock situation: (1) exynos_g2d_exec_ioctl() prepares a runqueue node and calls g2d_exec_runqueue() (2) g2d_exec_runqueue() calls g2d_dma_start() which gets runtime PM sync (3) runtime PM core calls g2d_runtime_resume() (4) g2d_runtime_resume() calls g2d_exec_runqueue(), which loops back to (2) Due to mutexes that are in place, a deadlock situation is created.
