[0/8] Add support for Azoteq IQS620A/621/622/624/625

Message

This series adds support for six-channel members of the Azoteq ProxFusion
family of sensor devices: IQS620A, IQS621, IQS622, IQS624 and IQS625. Each
device integrates multiple sensor technologies in a single package.

A multi-function device (MFD) driver supports core functions common to all
devices, including device identification, firmware, interrupt handling and
runtime power management. The MFD driver is also responsible for adding all
product-specific sub-devices.

Each device supports self-capacitive, Hall-effect, and (in some cases) mutual-
inductive sensing. These functions represent keys or switches and are supported
by an input driver that covers all five devices. An assortment of pwm, hwmon
and iio drivers support device-specific functions.

This series was tested using the following development hardware: IQS620AEV04,
IQS621EV04, IQS622EV04 and IQS624/5EV04.
