i.MX: Standardize i.MX serial 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.

[PMM: Drop attempt to print the ram_addr of a memory region in
one DPRINTF, which (a) was using the wrong format string so
didn't build on 32-bit and (b) was incorrectly looking at a
private field of a MemoryRegion struct]
