c5e589a171 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

a370f60a58 mfd: rn5t618: Register restart handler
Use the PMIC's repower capability for reboots. Register a restart
handler and use a slightly elevated priority of 192 since the PMIC
has suprior reset capability (causing a system wide reset).

f41206c9fd mfd: rn5t618: Use devm_mfd_add_devices() for mfd_device registration
Use devm_mfd_add_devices() for MFD devices registration and remove
the call of mfd_remove_devices() from .remove callback to remove
MFD child-devices. This is done by managed device framework.

9bb9e29c78 mfd: Add Ricoh RN5T618 PMIC core driver
Ricoh RN5T618 is a power management IC which integrates 3 step-down
DCDC converters, 7 low-dropout regulators, a Li-ion battery charger,
fuel gauge, ADC, GPIOs and a watchdog timer.

This commit adds a MFD core driver to support the I2C communication
with the device.
