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. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
