AN30259A is a 3-channel LED driver which uses I2C. It supports timed
operation via an internal PWM clock, and variable brightness. This
driver offers support for basic hardware-based blinking and brightness
control.

PC Engines apu3 is an improved version of the apu2, using the same SoC
and almost everything else.

This patch reuses as much as possible from the apu2 definitions, to
avoid redundancy.

Introduce the family of LED devices that can
drive a torch, strobe or IR LED.

The LED driver can be configured with a strobe
timer to execute a strobe flash.  The IR LED
brightness is controlled via the torch brightness
register.

LED drivers can be found here:

Driver obtains LED devices according to system configuration and creates
devices in form: "devicename:color:function", like
The full path is to be:
/sys/class/leds/mlxreg\:status\:amber/brightness
After timer trigger activation:
echo timer > /sys/class/leds/mlxreg\:status\:amber/trigger
Attributes for LED blinking will appaer in sysfs infrastructure:
/sys/class/leds/mlxreg\:status\:amber/delay_off
/sys/class/leds/mlxreg\:status\:amber/delay_on

LED setting is controlled through the on-board programmable devices,
which exports its register map. This device could be attached to any
bus type, for which register mapping is supported.

Update the driver to conform with the LED framework:
 - use devm_led_classdev_register
 - destroy mutex on exit
 - remove dependency on CONFIG_OF in the driver and move
   to the Kconfig
 - update the MODULE_LICENSE to GPL v2
 - remove setting of MAX brightness as the LED framework
   does this.
