[PATCH 5.10.y-cip 02/61] dt-bindings: net: renesas,etheravb: Fix optional second clock name

Lad Prabhakar

From: Geert Uytterhoeven <geert+renesas@...>

commit 6799e3f281e962628be531e8331bacd05b866134 upstream.

If the optional "clock-names" property is present, but the optional TXC
reference clock is not, "make dtbs_check" complains:

ethernet@e6800000: clock-names: ['fck'] is too short

Fix this by declaring that a single clock name is valid.
While at it, drop the superfluous upper limit on the number of clocks,
as it is implied by the list of descriptions.
