We had only DRM_INFO() and DRM_ERROR(), whereas the underlying printk()
provides several other useful intermediate levels such as NOTICE and
WARNING. So this patch fills out the set by providing both regular and
once-only macros for each of the levels INFO, NOTICE, and WARNING, using
a common underlying macro that does all the token-pasting.
DRM_ERROR is unchanged, as it's not just a printk wrapper.

Fix whitespace, missing ## (Eric Engestrom)
