Commit 0c559bc8abfb ("dt-bindings: serial: restrict possible child node
names") exposed the Allwinner D1 devicetrees as users of unevaluated
properties, with a slew of similar warnings now appearing during
dtbs_check:
sun20i-d1-nezha.dtb: serial@2500400: Unevaluated properties are not allowed ('dma-names', 'dmas' were unexpected)
Document the missing properties.
Signed-off-by: Conor Dooley <conor.dooley@xxxxxxxxxxxxx>

The commit exposing it is in Rob's tree, but I figure this can go either
way as it has no dependancy.
