Subject: backlight: qcom-wled: Remove unnecessary 4th default string in WLED3
Git-commit: 96571489a06999bf5c62e2058622990734556f8f
Patch-mainline: v5.17-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225

The previous commit improves num_strings parsing to not go over the
maximum of 3 strings for WLED3 anymore.  Likewise this default index for
a hypothetical 4th string is invalid and could access registers that are
not mapped to the desired purpose.
Removing this value gets rid of undesired confusion and avoids the
possibility of accessing registers at this offset even if the 4th array
element is used by accident.
