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>;
