[PATCH net-next 3/9] dt-bindings: net: qcom,ethqos: add qcom,shikra-ethqos compatible

[Mohd Ayaan Anwar <mohd.anwar@oss.qualcomm.com>]

Shikra's EMAC requires two additional clocks for NOC interconnect
access (axi-noc, pcie-tile-axi-noc) beyond the standard four, and an
OPP table with required-opps to vote VDD_CX to SVS when the NOC clocks
are enabled.

Add qcom,shikra-ethqos to the compatible enum and use an if/else
block to constrain Shikra to exactly six clocks and require
operating-points-v2, while leaving existing compatibles unchanged.

Add the relevant compatible to the binding document for snps,dwmac as
well.
