drm: Simplify drm_printk to reduce object size quite a bit
Remove function name and special " *ERROR*" from argument list
$ size drivers/gpu/drm/built-in.o* (x86-32 defconfig, most drm selected)
text data bss dec hex filename
5635366 182579 14328 5832273 58fe51 drivers/gpu/drm/built-in.o.new
5779552 182579 14328 5976459 5b318b drivers/gpu/drm/built-in.o.old
Using "%ps", __builtin_return_address(0) is the same as "%s", __func__
except for static inlines, but it's more or less the same output.
Miscellanea:
o Convert args... to ##__VA_ARGS__
o The equivalent DRM_DEV_<FOO> macros are rarely used and not
worth conversion
