[PATCH -next] PM / devfreq: event: Fix return value check in exynos_nocp_parse_dt()

[weiyj_lk at 163.com]

From: Wei Yongjun <yongjun_wei at trendmicro.com.cn>

In case of error, the function platform_get_resource() returns NULL
pointer not ERR_PTR(). Remove unneeded error handling on the result
of a call to platform_get_resource() since the value is passed to
devm_ioremap_resource().
