[PATCH] ARM: zx: Fix devm_ioremap_resource error detection code

[Amitoj Kaur Chawla]

Remove unnecessary error handling after the call to
platform_get_resource and fix error handling for devm_ioremap_resource

The Coccinelle semantic patch that was used to help find this is as
follows:
@@
expression e,e1;
statement S;
@@

*e = devm_ioremap_resource(...);
if (!e1) S
