[PR] sched: support smp function call [nuttx]
zyfeier opened a new pull request, #10934:
URL: https://github.com/apache/nuttx/pull/10934
## Summary
The smp function call allows specifying a function to be executed by another core. The wait parameter can be used to choose whether to wait or not for the other core to finish executing, it should be noted that there should be no waiting operations in the executed function.
This PR include:
1. Add smp function call support in sched;
2. ARM64 support smp function call, other architectures will be added gradually;
## Impact
NA
## Testing
board:
qemu-armv8a:nsh_smp enable CONFIG_SMP_CALL
test code:
```
int test_smp_call_func(void *arg)
{
syslog(0, "test_smp_call_func:%d\n", up_cpu_index());
syslog_flush();
return 0;
}
int test_smp_call(int argc, FAR char *argv[])
{
nxsched_smp_call_single(1, test_smp_call_func, NULL, false);
nxsched_smp_call_single(1, test_smp_call_func, NULL, true);
nxsched_smp_call(0xf, test_smp_call_func, NULL, false);
nxsched_smp_call(0xf, test_smp_call_func, NULL, true);
}
```

> @zyfeier I think a similar testing should be included into ostest (including some why to detect it was ran in the right core) and executed when CONFIG_SMP_CALL is enabled.
Ok, i'll add test case to ostest.
