4.5-stable review patch. If anyone has any objections, please let me know.

commit 456e8d53482537616899a146b706eccd095404e6 upstream.
The following commits: commit 3fa609755c11 ("ARM: omap2: restore OMAP4 barrier behaviour") commit f746929ffdc8 ("Revert "ARM: OMAP4: remove dead kconfig option OMAP4_ERRATA_I688"") and commit ea827ad5ffbb ("ARM: DRA7: Provide proper IO map table") came in around the same time, unfortunately this seem to have missed initializing the barrier for DRA7 platforms - omap5_map_io was reused for dra7 till it was split out by the last patch. barrier_init needs to be hence carried forward as it is valid for DRA7 family of processors as they are for OMAP5.
