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.
