dt-bindings: trivial-devices: fix Rohm BH2228FV compatible string

When Maxime originally added the BH2228FV to the spidev driver, he spelt
it incorrectly - the d should have been a b. That spelling was then
propagated to the binding when written by Krzysztof. Add a new, correctly
spelt compatible and advise against using the incorrectly spelling.
