t31: add XVI ISI-2010C device profile

[ArthurKoba]

Adds a device profile for the XVI ISI-2010C — Ingenic T31N, GalaxyCore GC2053, 64 MiB RAM, 8 MiB SPI NOR and wired Ethernet.

Board-specific configuration:

• GC2053 sensor selection.
• H.264 as the default codec for compatibility; H.265 was also tested successfully.
• PA16 / GPIO16 as the daylight sensor input.
• PB26 / GPIO58 and PB25 / GPIO57 for the bistable IR-cut filter.
• No SD/MMC, Wi-Fi or usable USB host path on the tested board.
• Unused motor/PWM modules are excluded.
• T31 audio support is retained.

The PCB includes the audio connector and supporting circuitry. The tested unit has no microphone or speaker fitted from the factory, but both audio capture and playback were verified by connecting external audio hardware to the existing interface.

Tested on a physical XVI ISI-2010C: firmware builds, flashes and boots successfully; Ethernet, GC2053 video, H.264/H.265 streaming, automatic day/night switching, IR-cut control, audio capture/playback and operation after reboot are working.

High-Level Assessment

The approach follows the repository’s established per-device profile structure while reusing the generic T31 kernel configuration and limiting board differences to a fragment, overlay, and exclusion list. A shared GC2053 profile would reduce some defconfig duplication but would incorrectly couple board-specific flash, networking, GPIO, and peripheral assumptions, so the current isolation is preferable.

• Introduces the Buildroot profile for the T31 platform, GC2053 sensor, and 8 MiB NOR layout. It selects the standard OpenIPC services, Majestic video stack, T31 drivers, audio codecs, WireGuard, and compressed root filesystem formats.

• Sets the board-specific upgrade image and GC2053 sensor. It enables daylight monitoring, maps the light sensor and bistable IR-cut GPIOs, and defaults video encoding to H.264 for compatibility.

Disable unsupported board peripherals and filesystems

• Adds a kernel configuration fragment disabling MMC, wireless, USB, FAT, and VFAT support because the tested board exposes none of those facilities.
