[PATCH 1/2] regulator: lp8788: Remove lp8788_dldo_id and lp8788_aldo_id arrays

[Axel Lin]

The id for DLDOx matches the entries in enum lp8788_ldo_id and it's easy to
calculate the id for ALDOx. Thus remove lp8788_dldo_id and lp8788_aldo_id
arrays.

[PATCH 2/2] regulator: lp8788: Implement list_voltage for lp8788_ldo_voltage_fixed_ops

[Axel Lin]

For fixed voltage, we can just set min_uV and use regulator_list_voltage_linear
for list_voltage callback. Regulator core will call list_voltage(rdev, 0) if
both get_voltage get_voltage_sel are not implemented. Thus we can also remove
lp8788_ldo_fixed_get_voltage() function.
