accel/habanalabs: remove Gaudi1 multi MSI code
Multi MSI interrupts aren't working in Gaudi1 and because of that,
we are only using a single MSI interrupt. Therefore, let's remove this
dead code in

Now that CQ-completion based jobs do not trigger a reset upon failure,

accel/habanalabs: return tlb inv error code upon failure
Now that CQ-completion based jobs do not trigger a reset upon failure,
failure of such jobs (e.g., MMU cache invalidation) should be handled
by the caller itself depending on the error code returned to it.

accel/habanalabs: assert return value of hw_fini
Since hw_fini return error code for failure indication, we should
check its return value. Currently it might only fail upon soft-reset

accel/habanalabs: assert return value of hw_fini
Since hw_fini return error code for failure indication, we should
check its return value. Currently it might only fail upon soft-reset
from hl_device_reset. Later patch will add hw_fini failure in case of
polling timeout in hard-reset.

habanalabs: add uapi to flush inbound HBM transactions
When doing p2p with a NIC device, the NIC needs to make sure all the
writes to the HBM (through the PCI bar of the Gaudi device) were
flushed.
habanalabs: add uapi to flush inbound HBM transactions
When doing p2p with a NIC device, the NIC needs to make sure all the
writes to the HBM (through the PCI bar of the Gaudi device) were
flushed.
It can be done by either the NIC or the host reading through the PCI
bar.
To support the host side, we supply a simple uapi to perform this flush
through the driver, because the user can't create such a transaction
by itself (the PCI bar isn't exposed to normal users).
