spi: dt-bindings: atmel,at91rm9200-spi: fix broken sam9x7 compatible

Commit a3eb954 ("spi: dt-bindings: atmel,at91rm9200-spi: add sam9x7
compatible") adding sam9x7 compatible did not make any sense as it added
new compatible into middle of existing compatible list.  The intention
was probably to add new set of compatibles with sam9x7 as first one.
