Subject: [PATCH 16/17] arm64: dts: r8a77965-salvator-xs: Add DU external dot clocks

From: Takeshi Kihara <takeshi.kihara.df@...esas.com>

The DU1 external dot clock is provided by the fixed frequency clock
generator X21, while the DU0 and DU3 clocks are provided by the
programmable Versaclock6 clock generator.
