core/riscv-rv32i: dump panic info on console channel
The panic information currently dumps by debug_print API which
implemented on SCP UART. This implies that the panic information
can only be observed on SCP UART. We cannot have any information
about crashed SCP on non-development environment.
Add a new panic API to dump information on console channel, so that
panic information can be transmitted to kernel side via host command.
