Fabio Estevam 444a7c3bb8 ARM: mxs: Use a proper timeout mechanism 
Introduce a function for checking the busy bits of CLKCTRL register that
uses a proper timeout mechanism.

Remove parts of code that use busy loops and replace them with the
mxs_clkctrl_timeout() function.

Tested on a mx28evk by performing audio playback.
