[Dfu-util] [PATCH] quirks: add AM261x device-specific manifest wait quirk

Hi,

This patch adds an AM261x-specific quirk to reduce the manifest wait time to 500ms.

The AM261x ROM DFU implementation resets before the default 1 second manifest wait expires, So applying the shorter wait enables reliable firmware downloads while preserving the existing behavior for all other devices

Comments and feedback are welcome.

Thanks, Bensen Bernard Texas Instruments
