Subject: [PATCH] PM / devfreq: rockchip-dfi: Fix an error message

There is a typo in the message. The clock name should be 'pclk_ddr_mon'.
Fix it.

While at it, switch to dev_err_probe() which is less verbose, filters
-EPROBE_DEFER, and log the error code in a human readable way.

This looks like a cut'n'paste typo from drivers/devfreq/rk3399_dmc.c
