arm: plat-omap: iommu: fix request_mem_region() error path
request_mem_region() error exit will leak ioremapped memory. Fix this by moving the ioremap() after request_mem_region(), which is the proper order to do this anyway. Signed-off-by: Aaro Koskinen <aaro.koskinen@nokia.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
