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".

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.
