soc: fsl: dpio: add a device_link at dpaa2_io_service_register
Automatically add a device link between the actual device requesting the
dpaa2_io_service_register and the underlying dpaa2_io used. This link
will ensure that when a DPIO device, which is indirectly used by other
devices, is unbound any consumer devices will be also unbound from their
drivers.
For example, any DPNI, bound to the dpaa2-eth driver, which is using
DPIO devices will be unbound before its supplier device.
Also, add a new parameter to the dpaa2_io_service_[de]register functions
to specify the requesting device (ie the consumer).
