Of the ~40 platforms in arch/arm64/Kconfig.platforms, there appear to be 5 that do select it.

I don't know about the deferred probe timeout, but I bisected the 6.5-rc4 breakage to this commit:
commit c720a1f5e6ee8cb39c28435efc0819cec84d6ee2 Author: Michal Simek <michal.simek@amd.com> Date: Mon May 22 16:59:48 2023 +0200
arm64: zynqmp: Describe TI phy as ethernet-phy-id
So, reverting that on master appears to correct the issue (together with setting CONFIG_RESET_CONTROLLER=y).
