[PATCH RFC 1/9] dt-bindings: net: qcom,ethqos: add qcom,shikra-ethqos compatible

[Mohd Ayaan Anwar]

Shikra's EMAC requires three additional clocks beyond the standard four
(axi, axi-noc, pcie-tile-axi-noc) for NOC interconnect voting.  Add the
compatible string and extend clock-names with a oneOf variant for this
seven-clock configuration.

The AXI clock appears twice (as "stmmaceth" and "axi") because the
stmmac core and the driver's NOC bulk-clock array each consume one
reference; CCF refcounting makes this safe.
