backlight: lp855x_bl: support new LP8555 device
LP8555 is one of the LP855x family devices. This device needs pre_init_device() and post_init_device() driver structure. It's same as LP8557, so the device configuration code is shared with LP8557. Backlight outputs are generated from dual DC-DC boost converters. It's configurable EPROM settings which are defined in the platform data. Driver documentation and device tree bindings are updated.
