[PATCH 3/5] dt-bindings: arm: microchip,sam9x60-pit64b : convert to DT schema

[Akhila YS <akhilayalmati@gmail.com>]

Convert Atmel Periodic interval timer of 64bit (PIT64b) binding to YAML
format.
Changes during conversion:
- Add missing compatible "microchip,sama7g5-pit64b" along with a fallback
compatible "microchip,sam9x60-pit64b".

+description:
+  The Microchip PIT64B is a 64-bit periodic interval timer used in
+  several modern Microchip ARM SoCs including SAM9X60, SAM9X7 and
+  SAMA7D65 families. It provides extended timing range, flexible
+  clock selection and supports both periodic and one-shot interrupt
+  generation modes.
