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.

+ - const: microchip,sam9x60-pit64b
+ - items:
+ - enum:
+ - microchip,sama7d65-pit64b
+ - microchip,sama7g5-pit64b
+ - microchip,sam9x7-pit64b
Same here, I'll adjust this list to be alphanumerically sorted, thus, microchip,sam9x7-pit64b first. Other than that:
