The state-regmap is initialized by devm_regmap_init_mmio().
So it's fine to use spin_lock rather than mutex to protct state-regmap rmw

If IS_ERR(state-regs) the .probe fails.
So IS_ERR(state-regs) test in exynos_dp_video_phy_pwr_isol() is not necessary.
exynos_dp_video_phy_pwr_isol() simply does a regmap_update_bits() call now,
just call regmap_update_bits() instead and return proper return value.
