The sdhci_bcm driver attach routine relies on bcm_dma already being attached, in order to allocate a DMA channel. However, both drivers attached at the default pass so this is not guaranteed. Newer RPI firmware exposes this assumption, and the result is a NULL-dereference in bcm_dma_allocate(). To fix this, use BUS_PASS_SUPPORTDEV for bcm_dma.
