When many wavefronts cause VM faults at the same time, it can
overwhelm the interrupt handler and cause IH ring overflows before
the driver can notify or kill the faulting application.

As a workaround I'm introducing limited per-VM fault credit. After
that number of VM faults have occurred, further VM faults are
filtered out at the prescreen stage of processing.

This depends on the PASID in the interrupt packet, so it currently
only works for KFD contexts.

I've no idea why this is like this, why store 64-bit fields
as a string, and then parse the strings, this is just over
engineered.

This is what I'd call slightly overengineered, we waste 40k on
storing a value that is write or end, when we could just use the
register value to denote end.

This split serves no purpose, and we can make a bunch of functions
static now.

There are lots of cases of this sort of split in the powerplay code,
please start cleaning them up. Ideally the function table is in the
same file as all the implementations used in it.

This patch provides a guarantee that the first n queues allocated by
an application will be on different pipes. Where n is the number of
pipes available from the hardware.

This helps avoid ring aliasing which can result in work executing in
time-sliced mode instead of truly parallel mode.
