ieee802154/adf7242: Driver for ADF7242 MAC IEEE802154

This driver has been sitting in the linux-zigbee[2] repository for a long
time. We updated it from time to time and made it available via our
github kernel repository. The Linux MAC802.15.4 support has improved a lot
since then. Thanks to all! So it’s finally time to upstream this driver.

The ADF7242 requires an add-on firmware for the automatic IEEE 802.15.4
operating modes. The firmware file is currently made available on the
ADF7242 wiki page here [1]

+* ADF7242 IEEE 802.15.4 *
+
+Required properties:
+  - compatible:         should be "adi,adf7242"
+  - spi-max-frequency:  maximal bus speed (12.5 MHz)
+  - reg:                the chipselect index
+  - interrupts:         the interrupt generated by the device via pin IRQ1.
+                        IRQ_TYPE_LEVEL_HIGH (4) or IRQ_TYPE_EDGE_FALLING (1)
+
+Example:
+
+        adf7242@0 {
+                compatible = "adi,adf7242";
+                spi-max-frequency = <10000000>;
+                reg = <0>;
+                interrupts = <98 IRQ_TYPE_LEVEL_HIGH>;
+                interrupt-parent = <&gpio3>;
+        };
