arm64: dts: meson: Add default timings for VPU

These timings can be used as a fallback for UHD HDMI monitors since
the A311D SoC HDMI transmitter supports only up to 1920x1080 resolution.
Any supported timings found in EDID will be used instead of these default
values.

The timing data derived from patch 0220-hdmi_edid_fail_try_full_hd.patch
from https://github.com/hyphop/khadas-uboot/archive/last.zip.
