ARM: mxs: Use a proper timeout mechanism

Browse source

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.
