The fdt_overlay_apply() function purports to support the edge cases where
an overlay has no fixups to be applied, or a base tree which has no
symbols (the latter can only work if the former is also true). However it
gets it wrong in a couple of small ways:
* In the no fixups case, it doesn't fail immediately, but will attempt
fdt_for_each_property_offset() giving -FDT_ERR_NOTFOUND as the node
offset, which will fail. Instead it should succeed immediately, since
there's nothing to do.
* In the case of no symbols, it again doesn't fail immediately. However
if there is an actual fixup it will fail with an unexpected error,
because -FDT_ERR_NOTFOUND is passed to fdt_getprop() when attempting to
look up the symbols. We should instead return -FDT_ERR_NOTFOUND
directly.
Both of these errors lead to the code returning misleading error codes in
failing cases.
