f44a31c337 procfs: add memory pressure notification support 
This is a memory monitoring interface implemented with reference to Linux's PSI (Pressure Stall Information),
which can send notifications when the system's remaining memory is below the threshold.

The following example code sets two different thresholds.
When the system memory is below 10MB, a notification is triggered.
When the system memory is below 20 MB, a notification (POLLPRI event) is triggered every 1s.

```
int main(int argc, FAR char *argv[])
{
  struct pollfd fds[2];
  int ret;

  if (argc == 2)
    {
      char *ptr = malloc(1024*1024*atoi(argv[1]));
      printf("Allocating %d MB\n", atoi(argv[1]));
      ptr[0] = 0;
      return 0;
    }

  fds[0].fd = open("/proc/pressure/memory", O_RDWR);
  fds[1].fd = open("/proc/pressure/memory", O_RDWR);
  fds[0].events = POLLPRI;
  fds[1].events = POLLPRI;

  dprintf(fds[0].fd, "%llu -1", 1024LLU*1024 * 10);
  dprintf(fds[1].fd, "%llu 1000000", 1024LLU*1024 * 20);

  while (1)
    {
      ret = poll(fds, 2, -1);
      if (ret > 0)
        {
          printf("Memory pressure: POLLPRI, %d\n", ret);
        }
    }

  return 0;
}
```

46b0f6d6ee fdt: Add initial FDT support and procfs for userspace export 
VELAPLATFO-12536

This provides the initial hooks for Flattened Device Tree support
with QEMU RV. It also provides a new procfs file that exposes the
fdt to userspace much like the /sys/firmware/fdt endpoint in Linux.
See https://www.kernel.org/doc/Documentation/ABI/testing/sysfs-firmware-ofw

Nodes in the fdt are not yet usable by the OS.
