we try to use it in the IOCTLs.

When the radeon driver resets a gpu, it attempts to test whether all the
rings can successfully handle an IB. If these rings fail to respond, the
process will wait forever. Another gpu reset can't happen at this point,
as the current reset holds a lock required to do so. Instead, make all
the IB tests run with a timeout, so the system can attempt to recover
in this case.
While this doesn't fix the underlying issue with card resets failing, it
gives the system a higher chance of recovering. These timeouts have been
confirmed to help both a Tathi and Hawaii card recover after a gpu reset.
This also adds a new function, radeon_fence_wait_timeout, that behaves like
fence_wait_timeout. It is used instead of fence_wait_timeout as it continues
to work during a reset. radeon_fence_wait is changed to be implemented
using this function.
V2:
- Changed the timeout to 1s, as the default 10s from radeon_wait_timeout was
too long. A timeout of 100ms was tested and found to be too short.
- Changed radeon_fence_wait_timeout to behave more like fence_wait_timeout.

Generally a good idea between VM sessions. We need a way to
detect VM pass-through in general and always run asic_init in
that case.

This table is found on boards that support SR-IOV. This will
be used to determine if the board supports SR-IOV and allow
the driver to take specific action in certain cases.

ACP IP have internal DMA controller, DW I2S controller and DSPs
as separate power tiles. DMA and I2S devices are added to generic
pm domain, so that entire IP can be powered off/on at appropriate
times. Unused DSPs are made to be powered off though they are powered
on during ACP pm domain power on sequence.
