The tilcdc driver fails to be built as a module because of extraneous
MODULE_DEVICE_TABLE entries:

Since the entire point of these entries is to make the module autoload
when one of the devices is present, it's enough to keep the one entry
for "ti,am33xx-tilcdc", which should always be there if any of the
others are.
