Subject: [PATCH] drm/tilcdc: Disable building as module

Attempts to compile tilcdc as module results in:

drivers/gpu/drm/tilcdc/tilcdc_slave.o:(.data+0x54): multiple definition of
`__mod_of_device_table'
drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here
drivers/gpu/drm/tilcdc/tilcdc_panel.o:(.data+0x54): multiple definition of
`__mod_of_device_table'
drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here
drivers/gpu/drm/tilcdc/tilcdc_drv.o:(.data+0x184): multiple definition of
`__mod_of_device_table'
drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here
make[5]: [drivers/gpu/drm/tilcdc/tilcdc.o] Error 1 (ignored)

It appears it was never even tried to build it as module, or the problem
would have been seen. So running this driver as module was never really
tested. Disable it. If really needed, the code wil require some structural
changes and in-depth testing, which can and should be done separately.
