Subject: habanalabs/gaudi: collect undefined opcode error info
when an undefined opcode error occurres, the driver collects
the relevant information from the Qman and stores it inside
the hdev data structure. An event fd indication is sent towards the
user space.
Note: another commit shall be followed which will add support to
read the error info by an ioctl.
