The generic platform device for CI drivers is probed by calling
ci_hdrc_probe. This is not the same device as the one for the specific
driver, so the of_node isn't the one we're looking into.
This result in not being able to probe the phys. Since all CI driver are
retrieving their phys in the specific code, this didn't impact any of
them yet.
Fixes it using the right of node pointer, by using dev-parent instead
of dev in phy get functions.
It is a correct fix, but the description need to be refined, it is
not related to of_node or node, it is related child/parent device.
