[PATCH] regulator: rpi-panel-v2: Fix missing OF dependency

[Marek Vasut]

Add missing OF dependency and drop of_match_ptr() use.
This fixes the following LKP report:

"
>> drivers/regulator/rpi-panel-v2-regulator.c:95:34: warning: 'rpi_panel_v2_dt_ids' defined but not used [-Wunused-const-variable=]
    static const struct of_device_id rpi_panel_v2_dt_ids[] = {
                                     ^~~~~~~~~~~~~~~~~~~
"
