From: Samuel Holland <samuel@sholland.org>

With idle_bias_on and suspend_bias_off, there are bias level transitions
that match the suspend/resume callbacks. However, there are also
transitions during probe (OFF => STANDBY) and removal (STANDBY => OFF).

By using the set_bias_level hook, the driver can have one copy of code
that would otherwise be duplicated between the probe/resume and
suspend/remove hooks.
