rGaa399ad3e554: bcm_dma: don't dereference NULL softc
rG07ccf71451d7: bcm_dma: don't dereference NULL softc
Summary

This file defines a small API to be used by other drivers. If any of
these functions are called before the bcm_dma device has attached we
should handle the error gracefully. Fix a formatting quirk while here.

The issue related to device attach order is fixed in PR 268835.
