3c6d6e0fbf drm: drm_printer: add __printf validation 
drm_printf does not currently use the compiler to verify
format and arguments.  Make it do so.

Miscellanea:

o Add appropriate #include files for __printf and struct va_format
o Convert dev_printk to dev_info

3d387d923c drm/printer: add debug printer 
Useful for dumping lots of data into dmesg, e.g. drm_mm.

v2: Fixup export_symbol line, I misplaced a hunk (Chris).

2d5e836de7 drm/print: Move kerneldoc next to definition 
kerneldoc expects the comment next to definitions, otherwise it can't
pick up exported vs. internal stuff.

This fixes a warning from the doc build done with:

$ make DOCBOOKS="" htmldocs

d8187177b0 drm: add helper for printing to log or seq_file 
Sometimes it is nice not to duplicate equivalent printk() and
seq_printf() code.

v2: simplify things w/ va_format, and use dev_printk, docs
