ARM: OMAP: Split plat-omap/i2c.c into mach-omap1 and mach-omap2
There's no need to keep the device related things in the common i2c.c as omap2+ is using hwmod. Split the code to mach-omap1 and mach-omap2 parts and only leave common code to plat-omap/i2c.c. Note that as omap1 only has one i2c controller, we can now remove the old device related macros. Reviewed-by: Shubhrajyoti D <shubhrajyoti@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
