cpufreq: i.MX6: -EPROBE_DEFER fixes

[Sascha Hauer]

The i.MX6 cpufreq driver can't cope with -EPROBE_DEFER returned from
regulator_get/clk_get. This series fix that and some other small issues.

This series supersedes
[PATCH 1/2] cpufreq: imx: fix regulator_get error handling
[PATCH 2/2] cpufreq: imx: fix regulator_get_optional error handling
from Heiner Kallweit.
