drm: Reduce object size of DRM_DEV_<LEVEL> uses 

These macros are similar to the DRM_<LEVEL> with the addition
of a struct device * to the arguments.

Convert the single drm_dev_printk function into 2 separate functions.
drm_dev_printk with a KERN_<LEVEL> * for generic use and drm_dev_dbg
for conditional masked use.

Remove the __func__ argument and use __builtin_return_address(0) to be
similar to the DRM_<LEVEL> macros uses.

Convert the DRM_DEV_<LEVEL> macros to remove now unnecessary arguments
and use a consistent style.

These macros are rarely used in the generic gpu/drm code so the code
size does not change much for a defconfig, but when more drivers are
enabled, there is ~4k savings.

Many of these macros have no existing use at all.
