When calculating the system memory heap size, we report only 3/4 of
the total RAM size (or 1/2 for systems with less than 4GB of RAM).
In the memory budget extension query, we were reporting 90% of the
available system memory. If most of the memory in the system is free,
this could result in the total heap size being 3/4 of RAM, but the
memory available being 9/10 of RAM. But if the application tried to
allocate the memory reported as "available", it would exceed the heap
size. This can confuse some applications.
This patch makes the memory budget query clamp the available RAM to
the heap size, so it will never report more available than the heap
can provide. Unfortunately, this means that we'll report only 67.5%
of system memory as available (3/4 * 9/10). We may want to adjust
this estimate in the future.

This was mainly useful for older Gen7.x GPUs with 32-bit PPGTT, which
are now supported by hasvk rather than anv. The remaining platforms
which anv supports have 36, 47, or 48-bit PPGTT, which imposes a 3/4
limit of 48GB, 96TB, and 192TB of memory.
The GPUs with 36-bit PPGTT are Elkhart Lake and Jasper Lake, which
appear to be Atom CPUs that have a maximum supported memory
configuration of 32GB or less, so this limit should not matter there.
Nor is a multi-TB limit likely to matter on our other parts.
Drop this check to simplify the heap and memory budget calculations.

The SET_STREAM_OUT_BUFFER_LOAD_WRITE_POINTER registers have an
8 dword stride, but the code is only adding one dword between them
then the MME is calling an illegal method.
This is the simple fix, otherwise I think we'd have to multiply
somehow in the MME which seems pointless.
