dm: Print device name in dev_xxx like Linux

This adorns messages generated by dev_xxx with the device and driver
names. It also redirects dev_xxx to log when it is available. The names
of these functions very roughly take inspiration from Linux, but there is
no deeper correlation.

Both struct udevice and struct device are supported when logging, though
logging with struct device is no better than using log_xxx. The latter is
supported because of the large amount of existing code which logs with
struct device.
