t31: add XVI ISI-2010C device profile (T31N, GC2053, Ethernet only) (#166)

Ingenic T31N with a GalaxyCore GC2053, 64 MiB RAM, 8 MiB SPI NOR and wired Ethernet. Tested on the physical camera: builds, flashes and boots, with Ethernet, GC2053 video, H.264/H.265 streaming, automatic day/night switching, IR-cut control and audio capture/playback all working. The board has no radio, so the defconfig drops wireless-tools, wpa_supplicant and the Realtek driver that the nearest sibling carries, along with the QR onboarding helper that only exists to join a network. The kernel fragment turns off MMC, the wireless stack, USB and FAT rather than forking the generic T31 config. Because FAT goes with it, the profile also overrides /etc/modules: the stock list asks for vfat and exfat, which would no longer exist. The exclude list prunes motor.ko and the two sample_pwm modules. Those are built for every T31 board by ingenic-opensdk regardless of the pinned sensor, since they sit outside the sensor tree in the openingenic Kbuild, and no board in the tree had pruned them until now. There is no Kconfig symbol to disable them, so the exclude list is the only lever.
