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.
