It was only ever read from the device, and spit out to the kernel log

As the Neo devices were never actually supported by the driver, delete
the files that purported to control that type of device as they are not
needed.  This will let us shrink the driver a lot over time.

The "Neo" devices are never allowed to be bound to this driver, as they
are not in the valid list of PCI ids, so delete them from the driver as
the code in the probe function has no way to ever run.

Also delete the defines that are no longer used in relation to the Neo
devices, as they are not needed anymore.

The function that enables fsl-mc msi interrupts doesn't need
to be explicitly called from the fsl-mc bus driver initialization
routine.

Mark it to be independently called at system init; this is in line
with how things are handled by other GICv3 irqchip users.

gcc warns that the latest workqueue change leads to returning an
uninitialized variable:

drivers/staging/lustre/lnet/selftest/module.c: In function 'lnet_selftest_init':
drivers/staging/lustre/lnet/selftest/module.c:98:10: error: 'rc' may be used uninitialized in this function [-Werror=maybe-uninitialized]

A failure from alloc_ordered_workqueue() tends to indicate an
out-of-memory condition, so return -ENOMEM in both cases.
The second error path was a preexisting bug, where we always
returned zero after a kvmalloc_array() failure.

This is done on a quest to remove the 700+ different ways that files in
