driver-core: extend dev_printk() to pass structured data
Extends dev_printk() to attach a dictionary with a device identifier
and the driver core subsystem name to logged messages, which makes
dev_prink() reliable machine-readable. In addition to the printed
plain text message, it creates these properties:
SUBSYSTEM= - the driver-core subsytem name
DEVICE=
b12:8 - block dev_t
c127:3 - char dev_t
n8 - netdev ifindex
+sound:card0 - subsystem:devname
