[v2] ARM: EXYNOS: Remove unused DMC and CMU offset and its mapping

Commit Message

Pankaj Dubey Aug. 23, 2016, 6:01 a.m. UTC

Currently there is no user of DMC and CMU SFR offsets we can safely remove
mapping of their SFR address space and cleanup related offset macros from
mach-exynos

Changes since v1:
 - Removed unused CMU register mapping and related SFR macros and updated
