ARM: exynos: Fix boot with CONFIG_SUSPEND disabled
Exynos SMP code relies on PMU registers to be mapped via pmu_base_addr.
Those mapping is done in suspend.c:exynos_pmu_irq_init(), which is not
called if CONFIG_SUSPEND is disabled. Fix this by moving PMU mapping
creation to exynos.c:exynos_map_pmu(), which is called in all cases.
