This introduces a new LED driver that enables us to create a virtual LED
level meter device that consists of multiple LED devices by different
drivers.
Previously I developed the level meter feature for leds-gpio ("leds: gpio:
support multi-level brightness") [1]. Then I got a feedback from
Bjorn Andersson and made more generic new driver. This driver is also
inspired by led-backlight driver patchset [2] and actually requires
devm_of_led_get() function provided by the patchset.
