[PATCH -next] ARM: zx: use devm_platform_ioremap_resource

[Qinglang Miao]

Use the helper function that wraps the calls to platform_get_resource()
and devm_ioremap_resource() together. Note that error handling on the
result of a call to platform_get_resource() is unneeded either when the
value is passed to devm_ioremap_resource(), so remove it.
