[PATCH] omap: Move omap2_check_revision and omap_sram_init out of map_io

[Tony Lindgren]

With the early init changes we just want to map IO in map_io.
Both omap2_check_revision and omap_sram_init can be moved to
happen later in omap2_init_common_infrastructure.

Note that now we can now remove _omap2_map_common_io and remove
the extra flushes too as devicemaps_init will take care of it.

This is on top of the other early init related patches:

omap: hwmod: Populate _mpu_rt_va later on in omap_hwmod_late_init
omap2+: Fix omap_serial_early_init to work with init_early hook
omap2+: Make omap_hwmod_late_init into core_initcall
ARM: OMAP2: use early init hook
