Dmytro Prokopchuk b5497ad4a4 misra: allow discarding 'noreturn' during conversions
The conversion from a function pointer with the 'noreturn' attribute
('void noreturn (*)(...)') to a function pointer type ('void (*)(...)'
causes type incompatibility according to MISRA C Rule 11.1, which
forbids conversions between incompatible function pointer types.

The violation occurs at the call site:
    smp_call_function(halt_this_cpu, NULL, 0);
where 'halt_this_cpu' with type 'void noreturn (*)(void *)' is passed to
'smp_call_function' expecting function pointer of type 'void (*)(void *)'.

The 'noreturn' attribute does not change the function calling convention
or parameter handling at runtime, making the conversion safe.

For now, configure Eclair to just treat implicit conversions that lose
the "noreturn" attribute on a function 'void (*)(void*)' as safe.
