[RESEND PATCH v2 05/13] backlight: qcom-wled: Override default length with qcom,enabled-strings

[Marijn Suijten]

The length of qcom,enabled-strings as property array is enough to
determine the number of strings to be enabled, without needing to set
qcom,num-strings to override the default number of strings when less
than the default (which is also the maxium) is provided in DT.

Fixes: 775d2ffb4af6 ("backlight: qcom-wled: Restructure the driver for WLED3")
