i.MX: Standardize i.MX EPIT 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

We also replace IPRINTF with qemu_log_mask(). The qemu_log_mask() output
is following the same format as the above debug.
