Add hi3516dv100_lite_xm-n81820 device profile (MS41908M SPI lens)

[widgetii]

New profile for the Xiongmai HI3516D_N81820 (HiSilicon Hi3516A/D V100,
hi3516dv100 / family hi3516av100) — Sony IMX291 DC sensor, 16 MB NOR
(W25Q128), Ethernet-only — with a Panasonic MS41908M motorized zoom/focus
lens. Modeled on the proven hi3516ev300_lite_xm-85h50ai, but the motor is an
SPI stepper (/dev/spidev1.0), driven by majestic-af's ms41908 actuator —
not a UART Pelco lens — so there's no console-UART sharing to work around. All
facts confirmed on the live board (devid 00014914).

Files

• defconfig — from hi3516dv100_lite, plus BR2_PACKAGE_MAJESTIC_AF=y,
  BR2_OPENIPC_FLASH_SIZE="16", and the WiFi packages dropped (wired board).
• customizer.sh — sensor imx291 pinned to the DC ini
  (imx291_i2c_dc_1080p.ini; the MIPI default would give no video); autofocus
  enabled with actuator=ms41908 (the SPI backend isn't reachable via the
  pelco-only ptz_control env, so it's set directly in majestic config).
• excludes — keep libsns_imx291_dc.so + the DC ini, strip the other
  hi3516av100-osdrv sensors.
• README device-table row.

ci-matrix.py --self-test passes (device registered).

Dependency chain (for motors to work OOTB)

• majestic #905 (adds ms41908 to the isp.autofocus.actuator enum) — merged.
• firmware #2485 (bumps the majestic-af package to the ms41908 backend) —
  merged, so this device's image links the SPI-capable plugin.
• The prebuilt majestic.hi3516av100.* S3 binary must be rebuilt by the OpenIPC
  nightly to pick up the #905 enum before actuator=ms41908 validates on-device;
  /dev/spidev1.0 is present OOTB and the majestic binary already has the plugin
  loader. Final on-hardware flash/verify pending on the board.

High-Level Assessment

The dedicated profile follows the repository’s established device-specific configuration model and is appropriate for this board’s distinct flash, sensor, and actuator requirements. Reusing the generic profile would not safely enforce the IMX291 DC configuration or sensor pruning, while the existing Pelco environment path cannot address an SPI actuator; direct Majestic configuration is therefore the best approach.

• Pins the IMX291 DC/parallel sensor configuration, sets the device-specific upgrade URL, and enables Majestic autofocus with the ms41908 actuator. The settings avoid the incompatible MIPI default and Pelco-only control path before rebooting the camera.
