Ofir Bitton d7933b92c4 accel/habanalabs: add pci health check during heartbeat
[ Upstream commit d8b9cea584 ]

Currently upon a heartbeat failure, we don't know if the failure
is due to firmware hang or due to a bad PCI link. Hence, we
are reading a PCI config space register with a known value (vendor ID)
so we will know which of the two possibilities caused the heartbeat
failure.
