Add sama7d65 compatibility string.

Sama7d65 does not have a full last bank of PIO lines similar to the
Sama7g54 SoC. Sama7d65 only has 14 lines on the last PIO bank not the
full 32; adjusting the SoC attributes accordingly.

Hi,

dt-bindings already up-to-date with this new compatible string by:
https://lore.kernel.org/821255840c09d8d9cebbb1f2daaedd8a7c138875.1736522006.git.Ryan.Wanner@microchip.com
(even if still .txt)

Regards,
  Nicolas
