dt-bindings: mfd: rk808: Convert bindings to yaml

Convert the rk808 bindings into yaml format. clock-output-names varies
in maxItems depending on whether or not the clock-cells is 0 or 1. For
the rk805, rk809, and rk817. This preserves behavior with the existing
driver handling setting the clock for these specific PMICs. When this
driver is corrected and the devicetrees updated this logic can be
removed (since the rk805, rk808, and rk817 only have one actual clock).

Note this patch was previously sent as a series, all of the patches in
the series except this one have been committed to mainline.

-  outputs). See <dt-bindings/clock/rockchip,rk808.h> for clock IDs.
-

-Regulators: All the regulators of RK8XX to be instantiated shall be
-listed in a child node named 'regulators'. Each regulator is represented
-by a child node of the 'regulators' node.

-	regulator-name {
-		/* standard regulator bindings here */
-	};
-
-Following regulators of the RK805 PMIC regulators are supported. Note that
-the 'n' in regulator name, as in DCDC_REGn or LDOn, represents the DCDC or LDO
-number as described in RK805 datasheet.
-
-	- DCDC_REGn
-		- valid values for n are 1 to 4.

-
-It is necessary to configure three pins for both the RK809 and RK817, the three
-pins are "gpio_ts" "gpio_gt" "gpio_slp".
-	The gpio_gt and gpio_ts pins support the gpio function.
-	The gpio_slp pin is for controlling the pmic states, as below:
-		- reset
-		- power down
-		- sleep
-
-Standard regulator bindings are used inside regulator subnodes. Check
