ARM: OMAP2: Fix up interconnect barrier initialization for DRA7



The following commits:
commit 3fa60975 ("ARM: omap2: restore OMAP4 barrier behaviour")
commit f746929f ("Revert "ARM: OMAP4: remove dead kconfig option OMAP4_ERRATA_I688"")
and
commit ea827ad5 ("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.
