mfd: rn5t618: Add Ricoh RC5T619 PMIC support

The Ricoh RN5T567 is from the same family as the Ricoh RN5T618 is,
the differences are:

+ DCDC4/DCDC5
+ LDO7-10
+ Slightly different output voltage/currents
+ 32kHz Output
+ RTC
+ USB Charger detection

 * Ricoh RN5T567/RN5T618 PMIC
 
-Ricoh RN5T567/RN5T618 is a power management IC family which integrates
-3 to 4 step-down DCDC converters, 7 low-dropout regulators, GPIOs and
-a watchdog timer. The RN5T618 provides additionally a Li-ion battery
-charger, fuel gauge and an ADC. It can be controlled through an I2C
-interface.

 Required properties:
  - compatible: must be one of
                "ricoh,rn5t567"
                "ricoh,rn5t618"
+               "ricoh,rc5t619"
  - reg: the I2C slave address of the device
 
 Sub-nodes:
  - regulators: the node is required if the regulator functionality is
    needed. The valid regulator names are: DCDC1, DCDC2, DCDC3, DCDC4
-   (RN5T567), LDO1, LDO2, LDO3, LDO4, LDO5, LDORTC1 and LDORTC2.

+   LDO7-10 are specific to RC5T619.
    The common bindings for each individual regulator can be found in:
