[PATCH v2] ARM: exynos: Bring back reboot on Exynos5410

Since 8cfc7fdd33080e30b86d21b1a8c9ad0686427ddc
("ARM: EXYNOS: move restart code into pmu driver") PMU support is required
in order for the reboot to work. Unfortunately, there is currently no PMU
support for 5410.

This patch adds exynos5410-pmu to the list of recognized devices. It is
okay for the code to have empty struct exynos_pmu_data, in this case only
minimal support is enabled. This is enough for SWRESET to work.
