The core version of EMAC on qcs615 has minor differences compared to that
on sm8150. During the bring-up routine, the loopback bit needs to be set,
and the Power-On Reset (POR) status of the registers isn't entirely
consistent with sm8150 either.
Therefore, it should be treated as a separate entity rather than a
fallback option.

'revise description' is not very specific. 'Drop fallback compatible for 
qcom,qcs615-ethqos' would be better.

However, this is an ABI change. You could leave the binding/dts alone 
and only change the kernel driver to match on qcom,qcs615-ethqos to 
achieve what you need. If there's a reason why the ABI change is okay, 
then you need to detail that. Did the driver never work? Are there no 
users yet?
