backlight: qcom-wled: Provide enabled_strings default for WLED 4 and 5
Only WLED 3 sets a sensible default that allows operating this driver
with just qcom,num-strings in the DT; WLED 4 and 5 require
qcom,enabled-strings to be provided otherwise enabled_strings remains
zero-initialized, resulting in every string-specific register write
(currently only the setup and config functions, brightness follows in a
future patch) to only configure the zero'th string multiple times.
