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.
