Converting dev_* to drm_* in amdgpu

[Koorosh Lahijani <kooroshlahijani@gmail.com>]

Hi,

I'm Koorosh a computer engineering student, I like to start learning
kernel development and I'm interested in the Linux graphics stack.

I like to take up the task of converting the dev_* logging macros to
their drm_* counterparts if this change is wanted in amdgpu driver.

One small question about the task, it is mentioned in
linux/Documentation/gpu/todo.rst:217 that the reason for using dev_*
macros is differentiating between instances of the same driver, should I
do anything special on the format string part for this or leaving it to
the first argument of drm_* macros is enough?

Regards,
Koorosh
