From: Fei Yang <fei.yang at intel.com>

The lite restore is a performance improvement feature which avoids
unnecessary context switch (flush, save and rstore) if the incoming
context has a ContextID matching that of the outgoing context. The
scheduling is done by the Guc firmware, so on the driver side it's
just a matter of setting corresponding GuC_CTL_FEATURE flag.
This is supposed to be enabled by default, thus the flag is set
unconditionally.
