Joe Perches db87086492 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.

Joe Perches 99a954874e drm: Reduce object size of DRM_ERROR and DRM_DEBUG uses
drm_printk is used for both DRM_ERROR and DRM_DEBUG with unnecessary
arguments that can be removed by creating separate functins.

Create specific functions for these calls to reduce x86/64 defconfig
size by ~20k.

Modify the existing macros to use the specific calls.

new:
$ size -t drivers/gpu/drm/built-in.a | tail -1
1876562	  44542	    995	1922099	 1d5433	(TOTALS)

old:

1897565	  44542	    995	1943102	 1da63e	(TOTALS)

Miscellanea:

o intel_display requires a change to use the specific calls.

Chris Wilson 79a5ad2fdb
drm: Enable pr_debug() for drm_printer
pr_debug() is conditionally compiled and requires either
dynamic-debugging to be enabled or for the code to opt-in using #define
DEBUG. Since drm_print provides a central debugging facility using
pr_debug(), make sure it will always produce output.

Joe Perches 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

Rob Clark d8187177b0 drm: add helper for printing to log or seq_file

seq_printf() code.
