The lite restore is a performance improvement feature which avoids
unnecessary full context save and restore if the task been switched
in is the same as the one been switched out. This is supposed to be
enabled by default.

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.
