dt-bindings: arm: sunxi: Fix incorrect '-' usage

Commit 6bc6bf8 ("dt-bindings: arm: sunxi: document Anbernic RG35XX
handheld gaming device variants") mistakenly added '-' on each line
which created empty (i.e. description only) schemas matching anything.
This causes validation to fail on all the root node compatibles as
there are multiple oneOf clauses passing.
