dt-bindings: serial: snps-dw-apb-uart: add dma & dma-names properties
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.
