Calling force_performance_level() from set_power_state()
doesn't work on some asics because the current power
state pointer has not been properly updated at that point.
Move the calls to force_performance_level() out of the
asic specific set_power_state() functions and into
the main power state sequence.
Fixes dpm resume on SI.

bapm is a power management feature for handling the
power budget between the CPU and GPU on APUs. This
patch adds support for enabling or disabling it.
For now disable it by default. Enabling it properly
requires quite a bit more work and will be addressed
in a separate patch.
This patch fixes hangs on boot on certain trinity
laptops when the system is on battery power.

using a working copy of the requested and current
power states.
