Add an engine driver to expose a "hub" FSI master - which has a set of control registers in the engine address space, and uses a chunk of the slave address space for actual FSI communication.

This option enables a FSI hub master driver. Hub is a type of FSI
|
|
master that is connected to the upstream master via a slave. Hubs
|
|
allow chaining of FSI links to an arbitrary depth. This allows for
|
|
a high target device fanout.
