Currently the codec does not work in the CONFIG_PM=n case because the regulators and clock are kept disabled.
Allow the codec to be functional by calling wm8962_runtime_resume() when CONFIG_PM=n.
Tested on a imx6sl-evk in the CONFIG_PM=y and CONFIG_PM=n cases.

Probably there is a better solution, hence I am sending it as RFC.
Thanks
