i.MX: Standardize i.MX CCM debug
The goal is to have debug code always compiled during build. We standardize all debug output on the following format: [QOM_TYPE_NAME]reporting_function: debug message The qemu_log_mask() output is following the same format as the above debug. Adding some missing qemu_log_mask call for bad registers.
