    dt-bindings: PCI: mediatek-gen3: Allow exact number of clocks only

    In MediaTek PCIe gen3 bindings, "clocks" accepts a range of 1-6 clocks
    across all SoCs. But in practice, each SoC requires a particular number of
    clocks as defined in "clock-names", and the length of "clocks" and
    "clock-names" can be inconsistent with current bindings.

    For example:

      - MT8188, MT8192 and MT8195 all require 6 clocks, while the bindings
        accept 4-6 clocks.

      - MT7986 requires 4 clocks, while the bindings accept 4-6 clocks.

    Update minItems and maxItems properties for individual SoCs as needed to
    only accept the correct number of clocks.
