media: coda: Clarify device registered log

Instead of printing just the device type, let's use
the device name, which makes the message more useful.

With this commit, the messages shown when the driver
is registered are:

coda 2040000.vpu: Firmware code revision: 570363
coda 2040000.vpu: Initialized CODA960.
coda 2040000.vpu: Firmware version: 3.1.1
coda 2040000.vpu: coda-jpeg-encoder registered as video0
coda 2040000.vpu: coda-jpeg-decoder registered as video1
coda 2040000.vpu: coda-video-encoder registered as video2
coda 2040000.vpu: coda-video-decoder registered as video3
