As this driver can now be compiled for ARM64, we get a new warning as a result of passing a DMA filter data pointer through an 'int':
sound/soc/sh/fsi.c: In function 'fsi_dma_probe': sound/soc/sh/fsi.c:1372:24: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] shdma_chan_filter, (void *)io->dma_id,
We already know that we only need the legacy filter function on arch/sh, so we can hide the legacy DMA interface function behind an #ifdef. This has the other advantage of no longer depending on the shdma_chan_filter function to be visible.
