Changes in v2:
 - Fixed description in mediatek,mt6685-clock.yaml

Some new PMICs, Clock IC and combos are complex SPMI 2.0 devices that
contain multiple IPs, including clock controllers.

This series expands the MediaTek clock helpers to allow registering
clock controllers over SPMI, and adds a clock driver for the MT6685
SCK_TOP clock controller.

For now, only gate clocks are supported to reduce the complexity of
this change.

NOTE: This series depends on series [1] "SPMI: Implement sub-devices
and migrate drivers"
