[Nouveau] [PATCH 1/2] drm/nouveau: Add new logging function nv_cli_printk
NV_PRINTK is a macro that adds the "%s: ", nouveau_cli.name to
logging output.
Save a few KB by creating a specific function to add that name
and change the users of theh NV_PRINTK macros to use the new
logging function.

[Nouveau] [PATCH 2/2] drm/nouveau: Convert NV_PRINTK macros and uses to new nv_cli_<level> macros
Use a more common logging style and reduce object size by calling
the nouveau_cli_printk function.
(size -t drivers/gpu/drm/nouveau/built-in.a x86/64 defconfig with nouveau)
text data bss dec hex filename
1736437 108484 1048 1845969 1c2ad1 (TOTALS) (new)
1737254 108484 1048 1846786 1c2e02 (TOTALS) (old)
Miscellanea:
o Add nv_cli_<level> macros that use nouveau_cli_printk
o Convert the NV_PRINTK uses to the new nv_cli_<level> macros
o Realign arguments of the conversions
