Marc Zyngier 66b3be3a7c net: stmmac: dwmac-meson8b: Add missing boundary to RGMII TX clock array
[ Upstream commit f0212a5ebfa6cd789ab47666b9cc169e6e688732 ]

Running with KASAN on a VIM3L systems leads to the following splat
when probing the Ethernet device:

==================================================================

Digging into this indeed shows that the clock divider array is
lacking a final fence, and that the clock subsystems goes in the
weeds. Oh well.

Let's add the empty structure that indicates the end of the array.
