Vladimir Zapolskiy c5857e3f94 pwm: brcmstb: Fix check of devm_ioremap_resource() return code ...

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.
