Subject: [PATCH 17/34] greybus: arche-ctrl: move device table to its right location

From: Arnd Bergmann <arnd@...db.de>

The arche-ctrl has two platform drivers and three of_device_id tables,
but one table is only used for the the module loader, while the other
two seem to be associated with their drivers.

This leads to a W=1 warning when the driver is built-in:

drivers/staging/greybus/arche-platform.c:623:34: error: 'arche_combined_id' defined but not used [-Werror=unused-const-variable=]
  623 | static const struct of_device_id arche_combined_id[] = {

Drop the extra table and register both tables that are actually
used as the ones for the module loader instead.

Fixes: 7b62b61c752a ("greybus: arche-ctrl: Don't expose driver internals to arche-platform driver")
