If an exception occurs on ARM or x86, we call panic() which will try to reset the board. Do the same on RISC-V.
To avoid -Werror=format-zero-length move a '\n' to the string passed to panic. We don't need a message here as depending on CONFIG_PANIC_HANG we will either see
### ERROR ### Please RESET the board ###
or
resetting ...
as next message.
