IMO removing CLK_OPS_PARENT_ENABLE is the right thing to do.

However if the hardware ends up does having a requirement that _some_
clock be enabled before touching the registers, then I think the
MTK clock library needs to be refactored, so that a register access
clock can be tied to the regmap. That might also require some work
on the syscon API.

Whether the hardware needs such a clock or not, we would need some input
from MediaTek. There's nothing in the datasheet on this.
