Subject: [PATCH v3 05/19] dlb2: add sched domain config and reset support

When a user requests to create a scheduling domain, the requested resources
are validated then reserved for the scheduling domain. This takes place in
dlb2_resource.c. Finally, the ioctl handler allocates an anonymous file
descriptor for the domain.

Once created, user-space can use its file descriptor for the scheduling
domain to configure the domain's resources (to be added in a subsequent
commit). User-space can also get additional file descriptors (for
multiprocess usage).

The driver maintains a reference count for each scheduling domain,
incrementing it each time user-space requests a file descriptor and
decrementing it in the file's release callback.

When the reference count transitions from 1->0 the driver automatically
resets the scheduling domain's resources and makes them available for use
by future applications. This ensures that applications that crash without
explicitly cleaning up do not orphan device resources.

Broadly speaking, the scheduling domain reset logic progressively disables
resources and flushes/drains them. The driver uses iosubmit_cmds512() to
flush load-balanced and directed ports. At the end of the domain reset
function, it resets hardware (register) state and software state.
