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

The surfaces that backup the GPU buffers have a boundary check that
considers that access to partial dwords are considered out-of-bounds.
For example, buffers with 1,3 16-bit elements has size 2 or 6 and the
last two bytes would always be read as 0 or its writting ignored.
The introduction of 16-bit types implies that we need to align the size
to 4-bytew multiples so that partial dwords could be read/written.
Adding an inconditional +2 size to buffers not being multiple of 2
solves this issue for the general cases of UBO or SSBO.
But, when unsized arrays of 16-bit elements are used it is not possible
to know if the size was padded or not. To solve this issue the
implementation calculates the needed size of the buffer surfaces,
as suggested by Jason:
surface_size = isl_align(buffer_size, 4) +
(isl_align(buffer_size, 4) - buffer_size)
So when we calculate backwards the buffer_size in the backend we
update the resinfo return value with:
buffer_size = (surface_size & ~3) - (surface_size & 3)
It is also exposed this buffer requirements when robust buffer access
is enabled so these buffer sizes recommend being multiple of 4.

We were calculating the total height of 2D surfaces by multiplying the
row pitch by the number of slices. This means that we actually request
slightly more space than actually needed since the padding on the last
slice is unnecessary. For tiled surfaces this is not likely to make a
difference. For linear surfaces, on the other hand, this means we may
require additional memory. In particular, this makes the i965 driver
reject EGL imports of buffers which do not have this extra padding.

The docs contain a bunch of commentary about the need to pad various
surfaces out to multiples of something or other. However, all of those
requirements are about avoiding GTT errors due to missing pages when the
data port or sampler accesses slightly out-of-bounds. However, because
the kernel already fills all the empty space in our GTT with the scratch
page, we never have to worry about faulting due to OOB reads. There are
two caveats to this:
1) There is some potential for issues with caches here if extra data
ends up in a cache we don't expect due to OOB reads. However,
because we always trash the entire cache whenever we need to move
anything between cache domains, this shouldn't be an issue.
2) There is a potential issue if a surface gets placed at the very top
of the GTT by the kernel. In this case, the hardware could
potentially end up trying to read past the top of the GTT. If it
nicely wraps around at the 48-bit (or 32-bit) boundary, then this
shouldn't be an issue thanks to the scratch page. If it doesn't,
then we need to come up with something to handle it.
Up until some of the GL move to ISL, having the padding code in there
just caused us to harmlessly use a bit more memory in Vulkan. However,
now that we're using ISL sizes to validate external dma-buf images,
these padding requirements are causing us to reject otherwise valid
images due to the size of the BO being too small.

try to get it working later.
