mt7986a.dtsi misses clock-names which are now required since support of
MT8192/MT8188/MT8195. This change also introduces a 6th clock which is
now needed for all pcie-gen3 dts.

i do not know how to map the clocks to the names...

mediatek-pcie-gen3.yaml:

  clock-names:
    items:
      - const: pl_250m
      - const: tl_26m
      - const: tl_96m
      - const: tl_32k
      - const: peri_26m
      - enum:
          - top_133m        # for MT8192
          - peri_mem        # for MT8188/MT8195

mt7986a.dtsi:

	clocks = <&infracfg CLK_INFRA_PCIE_SEL>,
		 <&infracfg CLK_INFRA_IPCIE_CK>,
		 <&infracfg CLK_INFRA_IPCIE_PIPE_CK>,
		 <&infracfg CLK_INFRA_IPCIER_CK>,
		 <&infracfg CLK_INFRA_IPCIEB_CK>;
