Before suspend, the sysclock select pll out as source, after resume
sysclock select the mlck as the source, so the sample rate is changed
the sound's pitch is shifted.
The issue is caused by the commit c1845da3d08de6cf2642fec74f7a46d05de6314d
Which removed the wm8960_configure_clocking() when bias level changes
from STANDBY to PREPARE, this patch is to add it back.
