media: coda: Clarify interrupt registered name

Make interrupt naming more consistent by using a common
pattern for video and jpeg interrupts.

With this commit, interrupts are shown as:

29:          0          0       GPC  12 Level     coda-video
30:          0          0       GPC   3 Level     coda-jpeg
