Vladimir Zapolskiy 194de738b6 pwm: brcmstb: Fix check of devm_ioremap_resource() return code 
commit c5857e3f94ab2719dfac649a146cb5dd6f21fcf3 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.
