Subject: [PATCH] soc: samsung: exynos-pmu: Fix compilation when nothing selects CONFIG_MFD_CORE

Commit 93618e344a5e ("soc: samsung: exynos-pmu: instantiate clkout driver as MFD")
adds a "devm_mfd_add_devices" call in the exynos-pmu driver which depends
on CONFIG_MFD_CORE. If no driver selects that config, the build will fail
if CONFIG_EXYNOS_PMU is enabled with the following error:
drivers/soc/samsung/exynos-pmu.c:137: undefined reference to `devm_mfd_add_devices'

Fix this by making CONFIG_EXYNOS_PMU select CONFIG_MFD_CORE.
