[PATCH v2 06/15] media: microchip-isc: set SAM9X7 maximum resolution to 2560x1920

[Balakrishnan Sambath <balakrishnan.s@microchip.com>]

SAM9X7 XISC uses the same image processing pipeline as SAMA7G5 but has
a smaller internal line buffer. The reduced RAM constrains the maximum
horizontal resolution to 2560 pixels (compared to 3264 on SAMA7G5),
resulting in a maximum capture resolution of 2560x1920.
