Vladimir Zapolskiy 75efb5fe5c crypto: ux500 - fix checks of error code returned by devm_ioremap_resource() ...

commit b62917a262 upstream.

The change fixes potential oops while accessing iomem on invalid
address, if devm_ioremap_resource() fails due to some reason.

The devm_ioremap_resource() function returns ERR_PTR() and never
returns NULL, which makes useless a following check for NULL.
