staging: fsl-dpaa2: mac: Added MAC / PHY interface driver.
This driver works as a proxy between phylib including phy drivers and
the MC firmware. It receives updates on link state changes from PHY
lib and forwards them to MC and receives interrupt from MC whenever
a request is made to change the link state.

With the new dprc_set_obj_irq() we can now program MSIS in the device
in the callback invoked from devm_request_threaded_irq().
Since this callback is invoked with interrupts disabled, we need to
use an atomic portal, instead of the root DPRC's built-in portal
which is non-atomic.

fsl-dpaa2: mac: Fix driver probing
The DPMAC probing function was broken in many ways. This patch adds
the following fixes:
- Look up PHY nodes based on the phy-handle property of the respective
DPMAC node;
- Defer DPMAC device probing until the MDIO MUX driver probes first (we
depend on that for configuring the PHYs on PCIe riser cards on
LS2085A QDS boards.
- Add Kconfig dependencies on XGMAC_MDIO and MDIO_BUS_MUX_MMIOREG.

fsl-dpaa2: mac: Fix interrupt handling
The DPMAC has two interrupt events muxed on a single interrupt line.
Both the PHY and the DPNI can initiate a link event.
When the link event is initiated by the PHY (possibly as the effect of an
earlier link change request initiated by a DPNI), we must make sure
dpmac_set_link_state() is explicitly called in order for the event to be
propagated (back) to the DPNI.
Finally, DPMAC interrupt mask has to be explicitly specified before calling
dpmac_set_irq_enabled().
