Since "/firmware" does not have its own "compatible" property as it's
just collection of nodes representing firmware interface, it's sub-nodes
are not populated during system initialization.

Currently different firmware drivers search the /firmware/ node and
populate the sub-node devices selectively. Instead we can populate
the /firmware/ node during init to avoid more drivers continuing to
populate the devices selectively.

To generalize the solution this patch populates the /firmware/ node
explicitly from of_platform_default_populate_init().

You had concernsin the past and I mentioned that firmware interface to
user-space *has* to continue in /sys/firmware, but he platform_device
management is internal to kernel.

Can we proceed with this change at-least for qcom and meson firmware
which are platform device already ? I can drop optee related changes.
