User will provide a nonce via the INFO ioctl, and will retrieve
the signed device info generated using given nonce.

accel/habanalabs/gaudi2: add eq health check using irq2023-10-09T09:37:21Zfarah kassabrifkassabri@habana.ai2023-08-23T09:36:25Zurn:sha1:764bfd138f359423b299b7bf3fcbabb56b981ef5
This is the second patch for applying the eq health check mechanism
which will add support for the interrupt flow for gaudi2 asic.
More info about the interrupt mechanism:
set a dedicated msix for the eq error interrupt, and add
interrupt handler for it.
when FW detects some issue with EQ like EQ_FULL, it'll
raise that interrupt and driver should reset the device.
Driver will inform the FW which msix index to use through
the already existing handshake mechanism which will
send msix info message to fw.

accel/habanalabs/gaudi2: handle eq health heartbeat check2023-10-09T09:37:21Zfarah kassabrifkassabri@habana.ai2023-08-08T09:56:47Zurn:sha1:7c4130e6ddd709be2033a6635c91d445cb2baea5
Add mechanism for fw eq health check. this will be done using two flows:
using the heartbeat mechanism and raising a dedicated interrupt to
indicate an eq failure like EQ full.
This patch will add implementation for the eq heartbeat for gaudi2 asic.
More info about the heartbeat mechanism:
Expand the heartbeat mechanism to monitor a new event that
will be sent from FW upon receiving heartbeat message.
that way driver can know that the eq is working or not.

accel/habanalabs: move cpucp interface to linux/habanalabs2023-10-09T09:37:21ZDavid Meriindmeriin@habana.ai2023-07-24T20:30:44Zurn:sha1:2b76129c5ae710423cfb55806803341af6a403a7
The CPUCP interface is moved to a shared folder outside of accel as
a pre-requisite to upstream the NIC drivers that will also include
this file.
