Subject: [PATCH] phy: samsung-ufs: switch back to syscon_regmap_lookup_by_phandle()

Now exynos-pmu can register its custom regmap for gs101 via
of_syscon_register_regmap() we can switch back to the standard
syscon_regmap_lookup_by_phandle() api for obtaining the regmap.

Additionally add a Kconfig dependency for MFD_SYSCON.
