riscv defconfig CONFIG_PM/macb/generic PHY regression in v5.18-rc1

What clock is driving the PHY? Sometimes the SoC outputs a clock to
the PHY, and the PHY will not work without it. Sometimes it is the
other way around, the PHY outputs a clock to SoC, so this might not be
your issue.

Maybe PM is turning the clock off because nothing is using it?
