dma: Fix compiler warning
of_dma_is_coherent() returns an undefined value on unexpected return
values of of_dma_get_coherence():
drivers/of/platform.c: In function 'of_dma_is_coherent':
drivers/of/platform.c:128:1: warning: control reaches end of non-void function [-Wreturn-type]
This cannot be reached so just add a BUG() to silence the compiler.
