Subject: [PATCH] Add tuned power profile defaults

Make PPD power profiles go through our own tuned wrappers.
Keep the wrappers close to upstream TuneD defaults while adding PCIe ASPM
settings per profile, and use a Performance profile more suited for
desktops instead of inheriting throughput-performance's server-esque VM
and disk tuning, which probably does more harm than good by messing with
dirty_bytes and disk readahead - wasting cache.
