The idea is to direct the output to some other (unused) UART port.

Also if one doesn't select DEBUG_LL, I wonder if it makes sense to
expect the "Uncompressing .... " message, which too is just dumping
raw data onto UART. So another option might be to simply use
CONFIG_DEBUG_LL instead of CONFIG_DEBUG_DECOMPRESS_KERNEL ?
