The device info initializer makes several fuctions internal:
- handling of device override
- updating topology from kernel information
The implementation file is slightly reordered due to the renamed
functions being static.

Rename the original device info initialization routine so callers
don't mistakenly call the wrong one:
gen_get_device_info_from_fd:
Queries kernel for full device info, including topology
details.
gen_get_device_info_from_pci_id:
Partially initializes device info based on PCI ID lookup, when
the kernel is not available.

With perf queries, initializing the device info is much more complex
than just getting a PCI ID and calling gen_get_device_info. This commit
adds a new gen_get_device_info_from_fd helper in common code which does
all of the requisite kernel queries to get device info including all of
the topology information.

With the introduction of asymmetric slices in CNL, we cannot rely on
the previous SUBSLICE_MASK getparam to tell userspace what subslices
are available.
We introduce a new uAPI in the kernel driver to report exactly what
part of the GPU are fused and require this to be available on Gen10+.
Prior generations can continue to rely on GETPARAM on older kernels.
This patch is quite a lot of code because we have to support lots of
different kernel versions, ranging from not providing any information
(for Haswell on 4.13 through 4.17), to being able to query through
GETPARAM (for gen8/9 on 4.13 through 4.17), to finally requiring 4.17
for Gen10+.
This change stores topology information in a unified way on
brw_context.topology from the various kernel APIs. And then generates
the appropriate values for the equations from that unified topology.

There are a couple of ways we can get the fusing information from the
kernel :
- Through DRM_I915_GETPARAM with the SLICE_MASK/SUBSLICE_MASK
parameters
- Through the new DRM_IOCTL_I915_QUERY by requesting the
DRM_I915_QUERY_TOPOLOGY_INFO
The second method is more accurate and also gives us the EUs fusing
masks. It's also a requirement for CNL as this platform has asymetric
subslices and the first method SUBSLICE_MASK value is assumed uniform
across slices.

This will be reused to store values reported by the kernel. The main
use case will be for use as the input values of the metric sets
equations for the INTEL_performance_queries extension. By storing this
information in the gen_device_info we make this non GL specific so
this can be reused by Vulkan if we ever have an equivalent extension.

Split out the device info so isl doesn't depend on intel/common. Now
it will depend on the new intel/dev device info lib.
This will allow the decoder in intel/common to use isl, allowing us to
apply Ken's patch that removes the genxml duplication of surface
formats.
