Add new struct drm_device based logging macros modeled after the core kernel device based logging macros. These would be preferred over the drm printk and struct device based macros in drm code, where possible. We have existing drm specific struct device based logging functions, but they are too verbose to use for two main reasons: * The names are unnecessarily long, for example DRM_DEV_DEBUG_KMS(). * The use of struct device over struct drm_device is too generic for most users, leading to an extra dereference. For example: DRM_DEV_DEBUG_KMS(drm->dev, "Hello, world\n"); vs. drm_dbg_kms(drm, "Hello, world\n"); It's a matter of taste, but the SHOUTING UPPERCASE has been argued to be less readable than lowercase. Some names are changed from old DRM names to be based on the core kernel logging functions. For example, NOTE -> notice, ERROR -> err, DEBUG -> dbg. Due to the conflation of DRM_DEBUG and DRM_DEBUG_DRIVER macro use (DRM_DEBUG is used widely in drivers though it's supposed to be a core debugging category), they are named as drm_dbg_core and drm_dbg, respectively. The drm_err and _once/_ratelimited variants no longer include the function name in order to be able to use the core device based logging macros. Arguably this is not a significant change; error messages should not be so common to be only distinguishable by the function name. Ratelimited debug logging macros are to be added later.
