ARM: EXYNOS: Fix kernel panic when unplugging CPU1 on exynos
A look at the code reveals use of S5P_VA_SYSRAM macro, in case of certain SoC revisions, which is not valid any longer, after SYSRAM started to be mapped dynamically. The new dynamic mapping is stored in sysram_base_addr variable, which is declared static in platsmp.c This fix makes sysram_base_addr non-static, declared it in common.h and used in pm.c instead of S5P_VA_SYSRAM.
