[PATCH v2 1/3] backlight: lp855x: Move device_config setting out of lp855x_configure()

[Hans de Goede]

Move the setting of the lp->cfg pointer to the chip specific
lp855x_device_config struct from lp855x_configure() to
lp855x_probe(), before calling lp855x_parse_dt().

This is a preperation patch for adding ACPI enumeration support.
