dmaengine: shdma: fix a build failure on platforms with no DMA support
On platforms with no support for the shdma dmaengine driver build is
currently failing with
drivers/built-in.o: In function `sh_mobile_sdhi_probe':
drivers/mmc/host/sh_mobile_sdhi.c:170: undefined reference to`shdma_chan_filter'
Fix the breakage by defining shdma_chan_filter to NULL in such
configurations.
