Use device coredump framework instead of print_hex_dump to support
FW crash dump. Pass data to the framework if preparing and dumping
are successful. The framework will take the ownership of the data.
The data will be freed after the framework determines its lifetime
is over. A new coredump will not work if the previous one still
exists.
