Listed above Allwinner SoCs has two SPI controllers. First is the regular
SPI controller and the second one has additional functionality for
MIPI-DBI Type C.

Add compatible strings for these controllers

So this is still not right: It allows:
"allwinner,sun20i-d1-spi-dbi", "allwinner,sun50i-r329-spi"
which it shouldn't, but more importantly disallows the three string
version that is introduced in patch 5/5, which makes dtbs_check fail.
So we need to fix this. I think the simplest is probably:

+      - items:
+          - enum:
+              - allwinner,sun20i-d1-spi
+              - allwinner,sun50i-r329-spi-dbi
+          - const: allwinner,sun50i-r329-spi
+      - items:
+          - const: allwinner,sun20i-d1-spi-dbi
+          - const: allwinner,sun50i-r329-spi-dbi
+          - const: allwinner,sun50i-r329-spi

Maybe there is a shorter sequence.
This assumes we go with the three-string combo, of course.

Cheers,
Andre
