arm64: dts: renesas: r8a779a0: Correct avb[01] reg sizes

[ Upstream commit 0c51912331f8ba5ce5fb52f46e340945160672a3 ]

All Ethernet AVB instances on R-Car V3U have registers related to UDP/IP
support, but the declared register blocks for the first two instances
are too small to cover them.

Fix this by extending the register block sizes.
