v2 (Anuj):
Rebased on master and updated pci ids
Remove redundant initialization of max_wm_threads to 64 * 12.
For gen9+ max_wm_threads are initialized in gen_get_device_info().
v3 (Anuj):
Move the patch to end of series.
Remove unused gt1, gt2, gt3 functions.
Remove l3_banks variable. Variable is now available on master.

All the "features" of the hardware are similar starting with GEN8, so remove as
much of the GEN9 uniqueness as possible. This makes implementing future gen
platforms a bit easier.

Prior to Skylake the Gen HW timestamps were driven by a 12.5MHz clock
with the convenient property of being able to scale by an integer (80)
to nanosecond units.
For Skylake the frequency is 12MHz or a scale factor of 83.333333
This updates gen_device_info to track a floating point timebase_scale
factor and makes corresponding _queryobj.c changes to no longer assume a
scale factor of 80 works across all gens.
Although the gen6_ code could have been been left alone, the changes
keep the code more comparable, and it now shares a few utility functions
for scaling raw timestamps and calculating deltas. The utility for
calculating deltas takes into account 32 or 36bit overflow depending on
the current kernel version.
Note: this leaves the timestamp handling of ARB_query_buffer_object
untouched, which continues to use an incorrect scale of 80 on Skylake
for now. This is more awkward to solve since the scaling is currently
done using a very limited uint64 ALU available to the command parser
that doesn't support multiply or divide where it's already taking a
large number of instructions just to effectively multiple by 80.
This fixes piglit arb_timer_query-timestamp-get on Skylake
v2: (Ken) Update timebase_scale for platforms past Skylake/Broxton too.

Most of the 3-D engine Kaby Lake is identical to Sky Lake. However, there
are a few small differences that we need to be able to detect.

We had missed a bit of errata - PS scratch needs to be computed as if
there were 4 subslices per slice, rather than 3.
Skylake Broxton Kabylake
GT1 GT2 GT3 GT4 2x6 3x6 GT1 GT1.5 GT2 GT3 GT4
Actual Slices 1 1 2 3 1 1 1 1 1 2 3
Total Subslices 3 3 6 9 2 3 2 3 3 6 9
Subsl. for PS Scratch 4 4 8 12 4 4 4 4 4 8 12
Note that Skylake GT1-3 already worked because we allocated 64 * 9
(trying to use a value that would work on GT4, with 9 subslices),
and the actual required values were 64 * 4 or 64 * 8. However, all
others (Skylake GT4, Broxton, and Kabylake GT1-4) underallocated,
which can lead to scratch writes trashing random process memory,
and rendering corruption or GPU hangs.
Fixes GPU hangs and rendering corruption on Skylake GT4 in shaders that
spill. Particularly, dEQP-GLES31.functional.ubo.all_per_block_buffers.*
now runs successfully with no hangs and renders correctly. This may
fix problems on Broxton and Kabylake as well.

Make gen_device_info a mutable structure so we can update the fields that
can be refined by querying the kernel (like subslices and EU numbers).
This patch does not make any functional change, it just makes
gen_get_device_info() fill a structure rather than returning a const
pointer.
