pc-bios/s390-ccw: Silence warning from Clang by marking panic() as noreturn
When compiling the s390-ccw bios with Clang, the compiler emits a warning:
pc-bios/s390-ccw/main.c:210:5: warning: variable 'found' is used uninitialized
whenever switch default is taken [-Wsometimes-uninitialized]
default:
^~~~~~~
pc-bios/s390-ccw/main.c:214:16: note: uninitialized use occurs here
IPL_assert(found, "Boot device not found\n");
^~~~~
It's a false positive, it only happens because Clang is not smart enough
to see that the panic() function in the "default:" case can never return.
Anyway, let's explicitely mark panic() with "noreturn" to shut up the
warning.
