rS303803: Add hw.fdt sysctl node.
Summary

Add hw.fdt sysctl node.
Make FDT blob available via opaque hw.fdt.dtb sysctl, if a DTB has been
installed by the time sysctls are registered.

Test Plan

Built image for RPi2 and booted on system. Able to grab the dtb using sysctl
and use dtc to convert the dtb to dts. Also did a diff between the original
dtb and the saved one and there was no difference.
