misc/pvpanic: add shutdown event definition
Shutdown requests are normally hardware dependent.
By extending pvpanic to also handle shutdown requests, guests can
submit such requests with an easily implementable and cross-platform
mechanism.
The event was added to the specification in qemu commit
73279cecca03 ("docs/specs/pvpanic: document shutdown event").

habanalabs: pass-through request from user to f/w
Add a uAPI, as part of the INFO IOCTL, to allow users to send
requests directly to f/w, according to a pre-defined set of opcodes
that the f/w exposes.
The f/w will put the result in a kernel-allocated buffer, which the
driver will then copy to the user-supplied buffer.
This will allow f/w tools to communicate directly with the f/w
without the need to add a new uAPI to the driver for each new type
of request.

habanalabs/gaudi2: capture RAZWI information
Added function to calculate possible engines which caused
RAZWI (read-only zero, write ignored), from a given router id or
module index.
When getting RAZWI via PSOC IP, first the router id is calculated
and then the possible engines that caused the RAZWI are calculated.
There is a possibility that the RAZWI initiator is not an engine. In
that case, it will not be included in possible engines as it
doesn't have an engine id.
RAZWI information is captured when receiving event from engine or via
PSOC IP.

habanalabs: add uapi to retrieve engines status
Currently, to get engines status, user needed to read debugfs file
with root permissions.
This new uapi allows user apace apps retrieve status, so for example,
in case of failure, status can be retrieved immediately by the
application itself which runs without root permissions.
