[PATCH v2] drivers: loongson: fix memory leak in loongson2_guts_probe

[Dongliang Mu]

drivers/soc/loongson/loongson2_guts.c:150 loongson2_guts_probe()
warn: 'guts->regs' from ioremap() not released on lines: 131,135,139,143.

Fix this by modifying ioremap to devm_ioremap.

Note that, this patch is not tested due to the loongson architecture.

Signed-off-by: Dongliang Mu <dzm91@xxxxxxxxxxx>

v1->v2: instead of modifying error handling code, directly change
ioremap to devm_ioremap.
