drm/lima: fix void pointer to enum lima_gpu_id cast warning
Create a simple data struct to hold compatible data so that we don't
have to do the casts to void pointer to hold data.
Fixes the following warning:
drivers/gpu/drm/lima/lima_drv.c:387:13: error: cast to smaller integer
type 'enum lima_gpu_id' from 'const void *'
