lib/igt_pm: Lib for power management
Move power management related code to a separate library.
Initially this is done only for workarounds that apply to external
components. Modify the users of such workarounds accordingly.
This currently involves HD audio and SATA link power management.
For SATA link PM there's also code to save the previous settings,
to allow for resetting the values after we've finished testing.
