[media] media: st-rc: Add ST remote control driver
This patch adds support to ST RC driver, which is basically a IR/UHF receiver and transmitter. This IP (IRB) is common across all the ST parts for settop box platforms. IRB is embedded in ST COMMS IP block. It supports both Rx & Tx functionality. This driver adds only Rx functionality via LIRC codec.

+Device-Tree bindings for ST IRB IP
+
+Required properties:
+ - compatible: Should contain "st,comms-irb".
+ - reg: Base physical address of the controller and length of memory
+ mapped region.
+ - interrupts: interrupt-specifier for the sole interrupt generated by
+ the device. The interrupt specifier format depends on the interrupt
+ controller parent.
+ - rx-mode: can be "infrared" or "uhf". This property specifies the L1
+ protocol used for receiving remote control signals. rx-mode should
+ be present iff the rx pins are wired up.
+ - tx-mode: should be "infrared". This property specifies the L1
+ protocol used for transmitting remote control signals. tx-mode should
+ be present iff the tx pins are wired up.
+
+Optional properties:
+ - pinctrl-names, pinctrl-0: the pincontrol settings to configure muxing
+ properly for IRB pins.
+ - clocks : phandle with clock-specifier pair for IRB.
+
+Example node:
+
+ rc: rc@fe518000 {
+ compatible = "st,comms-irb";
+ reg = <0xfe518000 0x234>;
+ interrupts = <0 203 0>;
+ rx-mode = "infrared";
+ };
