[PATCH v2 2/2] watchdog: s3c2410_wdt: use exynos_get_pmu_regmap_by_phandle() for PMU regs

[Peter Griffin]

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.
