dt-bindings: clock: Add SAMA7D65 PMC compatible string

Add the `microchip,sama7d65-pmc` compatible string to the existing binding,
since the SAMA7D65 PMC shares the same properties and clock requirements
as the SAMA7G5.

Export MCK3 and MCK5 to be accessed and referenced in DT to assign to
the clocks property for sama7d65 SoC.
