dt-bindings: mfd: Convert zii,rave-sp.txt to yaml format

Convert device binding doc zii,rave-sp.txt to yaml format.
Additional change:
- ref to other zii yaml files.
- remove rave-sp-hwmon and rave-sp-leds.

-Zodiac Inflight Innovations RAVE Supervisory Processor
-
-RAVE Supervisory Processor communicates with SoC over UART. It is
-expected that its Device Tree node is specified as a child of a node
-corresponding to UART controller used for communication.
-
-Required parent device properties:
-
- - compatible: Should be one of:
-	- "zii,rave-sp-niu"
-	- "zii,rave-sp-mezz"
-	- "zii,rave-sp-esb"
-	- "zii,rave-sp-rdu1"
-	- "zii,rave-sp-rdu2"
-
- - current-speed: Should be set to baud rate SP device is using
-
-RAVE SP consists of the following sub-devices:
-
-Device				 Description
-------				 -----------
-rave-sp-wdt			: Watchdog
-rave-sp-nvmem			: Interface to onboard EEPROM
-rave-sp-backlight		: Display backlight
-rave-sp-hwmon			: Interface to onboard hardware sensors
-rave-sp-leds			: Interface to onboard LEDs
-rave-sp-input			: Interface to onboard power button
-
-Example of usage:
-
-	rdu {
-		compatible = "zii,rave-sp-rdu2";
-		current-speed = <1000000>;
-
-		watchdog {
-			compatible = "zii,rave-sp-watchdog";
