Remove unnecessary function_name and prefix arguments.
Removing these arguments reduces object size.
prefix is used to add an "ERROR" prefix to the format for
DRM_DEV_ERROR and is an empty string for all other uses.
This string can be added instead by the DRM_DEV_ERROR macro.
function_name is used to emit the calling function.
This can be done by using %ps and __builtin_return_address(0).
