[PATCH v7 02/12] dt-bindings: microchip: atmel,at91rm9200-tcb: add sam9x7 compatible

[Varshini Rajendran <varshini.rajendran@microchip.com>]

Add support for sam9x7 device compatible with sama5d2 compatible as the
fallback as the sam9x7 SoC uses the same tcb IP as the latter.

Signed-off-by: Varshini Rajendran <varshini.rajendran@microchip.com>

Changes in v7:

- Elaborated the commit message with justifications to the fallback.
