[PATCH 03/10] backlight: qcom-wled: Override num-strings when enabled-strings is set

[Marijn Suijten]

DT-bindings do not specify num-strings as mandatory property, yet it is
required to be specified even if enabled-strings is used.  The length of
that property-array should already be enough to determine exactly which
and how many strings to enable.
