2ddf992179 drm/i915/tgl: Define MOCS entries for Tigerlake
The MOCS table is published as part of bspec, and versioned. Entries
are supposed to never be modified, but new ones can be added. Adding
entries increases table version. The patch includes version 1 entries.

Two of the 3 legacy entries used for gen9 are no longer expected to work.
Although we are changing the gen11 table, those changes are supposed to
be backward compatible since we are only touching previously undefined
entries.

v2: Add the missing entries in 49-51 range and replace "HW reserved"
    terminology to what it actually is: L1 is implicitly enabled
    (from Daniele)
v3: Use a different table for Tiger Lake since entries 0 and 1 are not
    the same (from Daniele)

a562772166 drm/i915: Inline engine->init_context into its caller
We only use the init_context vfunc once while recording the default
context state, and we use the same sequence in each backend (eliding
steps that do not apply). Remove the vfunc for simplicity and
de-duplication.

56e0f78e47 drm/i915/gt: Use caller provided forcewake for intel_mocs_init_engine
During post-reset resume, we call intel_mocs_init_engine to reinitialise
the MOCS registers. Suprisingly, especially when enhanced by lockdep,
the acquisition of the forcewake lock around each register write takes a
substantial portion of the reset time. We don't need to use the
individual forcewake here as we can assume that the caller is holding a
blanket forcewake for the reset&resume and the resume is serialised.

f4071997f1 drm/i915/ehl: Update MOCS table for EHL
EHL defines two new MOCS table entries but is otherwise compatible with
the ICL MOCS table.

These table entries (16 and 17) should still be considered unused for
ICL and as such their behavior remains undefined for that platform.

112ed2d31a drm/i915: Move GraphicsTechnology files under gt/
Start partitioning off the code that talks to the hardware (GT) from the
uapi layers and move the device facing code under gt/

One casualty is s/intel_ringbuffer.h/intel_engine.h/ with the plan to
subdivide that header and body further (and split out the submission
code from the ringbuffer and logical context handling). This patch aims
to be simple motion so git can fixup inflight patches with little mess.
