[PATCH] platform: cznic: turris-omnia-mcu: Add missing MODULE_DEVICE_TABLE()

The driver wires of_omnia_mcu_match into the i2c_driver's
.of_match_table but never exports it with MODULE_DEVICE_TABLE(), so no
module alias is generated and the module is not autoloaded when the MCU
is probed from the device tree.

Found by code inspection. Not tested on the hardware itself; with the
module built, the alias lookup

  $ modprobe -R 'of:Nsystem-controllerT(null)Ccznic,turris-omnia-mcu'

reports no match before this change and resolves to turris_omnia_mcu
after it.

Developed and tested on linux-next (next-20260826).  The affected file is
identical in v7.2, so this applies unchanged to mainline.
