fix(fdt): avoid output on missing DT property
When we use our fdt_read_uint32* helper functions, we output a warning
on not finding the requested property.
However non-existing properties are not that uncommon, and *trying* to
read such a property is actually a nice way of checking its existence.
Since we already return a specific error value in this case, the caller
can easily check this and give a more specific error message, if needed.
When the caller decides to properly handle the error (fallback, default
value, etc), a message on the console is quite misleading.
Demote the message to a VERBOSE, so normal builds will not spam the
console with pointless messages.
