Zhen Ni c19b29291f memory: samsung: exynos-srom: Fix of_iomap leak in exynos_srom_probe 
commit 6744085079 upstream.

The of_platform_populate() call at the end of the function has a
possible failure path, causing a resource leak.

Replace of_iomap() with devm_platform_ioremap_resource() to ensure
automatic cleanup of srom->reg_base.

This issue was detected by smatch static analysis:
drivers/memory/samsung/exynos-srom.c:155 exynos_srom_probe()warn:
'srom->reg_base' from of_iomap() not released on lines: 155.
