Subject: [PATCH 14/16] ARM: dts: at91: sama5d2_xplained: Add alias for DBGU

From: Tudor Ambarus <tudor.ambarus@...rochip.com>

The aliases should be defined in the board dts rather than in the
SoC dtsi. Don't rely on the aliases defined in the SoC dtsi and define
the alias for the Serial DBGU in the board dts file. sama5d2 boards use
the "serial0" alias for the Serial DBGU, do the same for sama5d2_xplained.
