backlight: aw99706: Fix DT property names to match binding

Browse source

The driver reads four tuning properties without the unit suffixes that
the binding mandates: "awinic,sw-freq" instead of "awinic,sw-freq-hz",
"awinic,sw-ilmt" instead of "awinic,sw-ilmt-microamp", "awinic,iled-max"
instead of "awinic,iled-max-microamp", and "awinic,uvlo-thres" instead
of "awinic,uvlo-thres-microvolt".

As a result, device_property_read_u32() never finds these properties in
a binding-conformant device tree and silently falls back to the compiled-in
defaults for switching frequency, switching current limit, max LED current,
and UVLO threshold.

Fix by aligning the property name strings in aw99706_dt_props[] with the
binding. No value/range changes are needed since both sides already use
the same units and enumerations.
