From: Arnd Bergmann <arnd@arndb.de>

After the recent rework, the structure is no longer referenced
anywhere and causes a build time warning:

drivers/regulator/rtq2208-regulator.c:222:35: error: 'rtq2208_regulator_ldo_ops' defined but not used [-Werror=unused-const-variable=]
  222 | static const struct regulator_ops rtq2208_regulator_ldo_ops = {
      |                                   ^~~~~~~~~~~~~~~~~~~~~~~~~

Remove it to get a clean build again.

I did not analyze the change to see if this is the only required change
or if there should still have been a reference instead. Please review
and confirm, or provide a different fix.

Fairly sure there should be a reference in _init_regulator_desc().

This is how 38bcec0e7cbb ("regulator: rtq2208: Fix
LDO discharge register and add vsel setting")] changed
the lines:

If the desc->ops was removed by accident, it seems
likely that desc->n_voltages also needs to be reverted.

In fact there's a series in flight which adds support for fixed voltage
mode and fixes this, though we'll need a separate fix for v6.10.
