dt-bindings: net: renesas,etheravb: Fix optional second clock name

Browse Source 
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.
