The thread counts and URB information are all speculative numbers that were
based on some CHV numbers at the time.
v2:
Originally this patch had PCI IDs. I've moved that to a new patch at the end of
the series.
Remove is_cherryview hack.
Add PCI ids. These match the ones defined in the kernel. The only one tested by
us is 0x0a84.
Capitalize the hex string (Mark)

Add values for gen7 & gen8. These are the number threads in a
subslice.

This also involves moving revision checking to screen creation time and
passing that into brw_get_device_info so that we can get the right
device_info for early versions of SKL. Since the only place we used
revision was to check for SIMD16 3-src instruction support, it's safe to
remove the revision field from brw_context.

This should cover all platforms prior to Skylake.

Based on a patch by Ville Syrjälä.
As usual, these are placeholder values; actual values will come later.

Since each kind of device has its own brw_device_info structure, we can
simply store the URB and thread limits there. This eliminates all the
large if-ladders, and simplifies the context initialization code quite a
bit.

The idea is that struct brw_device_info should store statically-known
information about hardware features. Using the new family name in the
PCI ID table, we can easily grab the right structure.
This is basically the equivalent of intel_device_info in the kernel.
This patch also makes the new structure available from intel_screen, but
nothing uses it. Right now, it looks very redundant with existing
fields, but that will change.
