pinctrl: samsung: Move retention control from mach-exynos to the pinctrl driver
This patch moves pad retention control from PMU driver to Exynos pin controller driver. This helps to avoid possible ordering and logical dependencies between machine, PMU and pin control code. Till now it worked fine only because sys_ops for PMU and pin controller were called in registration order. This is also a preparation for adding new features to Exynos pin controller driver, like runtime power management and suspending individual pin controllers, which might be a part of some power domain.
