The syscon_regmap_lookup_by_phandle() will never return NULL, thus use
IS_ERR() to validate the return value instead of IS_ERR_OR_NULL().

Use the new helper that wraps the calls to platform_get_resource()
and devm_ioremap_resource() together, which can simpify the code.

I did not see this patch in your clk tree (you only applied patch 2 in
this patch set), could you apply this patch if no other issues?
Thanks.
