dm: change dm_warn() message into debug() in uclass_add()
The command "dm uclass" tries to display all the UClasses, but some of them might be disabled by Kconfig. The function do_dm_dump_uclass() iterates over all the UClass IDs and calls uclass_get() for each of them. Then, it displays annoying message "Cannot find uclass for id ..." every time it fails to get the UClass. As a result, we get much noisier log for the "dm uclass" command. => dm uclass uclass 0: root - * root_driver @ bfb54028, seq 0, (req -1) Cannot find uclass for id 1: please add the UCLASS_DRIVER() ... Cannot find uclass for id 2: please add the UCLASS_DRIVER() ... Cannot find uclass for id 3: please add the UCLASS_DRIVER() ... Cannot find uclass for id 4: please add the UCLASS_DRIVER() ... Cannot find uclass for id 5: please add the UCLASS_DRIVER() ... Cannot find uclass for id 6: please add the UCLASS_DRIVER() ... This commit suppresses these warnings.
