bcm2835_sdhci: Clean up DMA resources on attach failure

bcm_sdhci_attach() allocates a DMA channel with bcm_dma_allocate()
before creating the bus_dma tag and map.  If a later initialization
step fails, the common error path releases the interrupt and memory
resources, but leaves the DMA channel allocated.

Call bcm_dma_free() for cleanup, as it already performs the required
internal checks and can therefore be invoked directly.
