watchdog: s3c2410_wdt: use exynos_get_pmu_regmap_by_phandle() for PMU regs
[ Upstream commit 746f0770f916e6c48e422d6a34e67eae16707f0e ]
Obtain the PMU regmap using the new API added to exynos-pmu driver rather
than syscon_regmap_lookup_by_phandle(). As this driver no longer depends
on mfd syscon remove that header and Kconfig dependency.
