Add the (previously omitted) pin data for the SMSC LAN89218 Ethernet chip
to the Blanche board's device tree: the chip's IRQ output is connected to
the SoC's IRQ0 pin and its nCS input is connected to the SoC's EX_CS0# pin.

Don't you need pinctrl for the other LBSC pins, like the address and data lines
(Ax and Dy)?


Unlike the chip selects, the address/data lines are not "monopolized" by a single device, so I'm not sure what to do with them...
