[PATCH 00/10] Engine initialization cleanup

[Matt Roper <matthew.d.roper@intel.com>]

A lot of our engine initialization code was inherited from i915 and
hasn't received too much cleanup since that time.  There's also some
inconsistencies between the main initialization path used on all
platforms, and the vestigial execlist code which isn't actually used but
still remains in the driver as dead code for now.  Let's clean things up
a bit and, where possible, move the required engine programming into the
RTP infrastructure so that it will be applied on both initialization
paths, and be dumpable/checkable via debugfs.

There's some more restructuring that should happen to more clearly
distinguish software state initialization from hardware initialization
(and re-initialization on various resets & suspend/resume), but I'll
leave that to a follow-up series to prevent this one from getting too
complicated.
