dmaengine: omap: hide filter_fn for built-in drivers

Browse Source 
It is not possible to reference the omap_dma_filter_fn filter
function from a built-in driver if the dmaengine driver itself
is a loadable module, which is a valid configuration otherwise.

This provides only the dummy alternative if the function
is referenced by a built-in driver to allow a successful
build. The filter function is only required by ATAGS based
platforms, which will continue to be broken after this change
for the bogus configuration. When booting from DT, with the
dma channels correctly listed there, it will work fine.
