regulator: Updates for v4.8 

A quiet regulator API release, a few new drivers and some fixes but
 nothing too notable.  There will also be some updates for the PWM
 regulator coming through the PWM tree which provide much smoother
 operation when taking over an already running PWM regulator after boot
 using some new PWM APIs.
 
  - Support for configuration of the initial suspend state from DT.
  - New drivers for Mediatek MT6323, Ricoh RN5T567 and X-Powers AXP809.

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. It can be controlled
through a I2C interface.
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.

Mediatek MT6323 Regulator Driver
All voltage regulators are defined as subnodes of the regulators node. A list
of regulators provided by this controller are defined as subnodes of the
PMIC's node. Each regulator is named according to its regulator type,
buck_<name> and ldo_<name>. The definition for each of these nodes is defined
using the standard binding for regulators at
Documentation/devicetree/bindings/regulator/regulator.txt.
The valid names for regulators are::
BUCK:
buck_vproc, buck_vsys, buck_vpa
LDO:
ldo_vtcxo, ldo_vcn28, ldo_vcn33_bt, ldo_vcn33_wifi, ldo_va, ldo_vcama,
