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.

70404ed0dc Merged in antmerlino/nuttx/iobinstrumentation (pull request #1001) 
Iobinstrumentation

* mm/iob: Introduces producer/consumer id to every iob call. This is so that the calls can be instrumented to monitor the IOB resources.

* iob instrumentation - Merges producer/consumer enumeration for simpler IOB user.

* fs/procfs: Starts adding support for /proc/iobinfo

* fs/procfs: Finishes first pass of simple IOB user stastics and /proc/iobinfo entry
