Bogus error messages on Apple Silicon

Randolph, Ilias,

After commit 623f6c5b6ab7fa2 ("boot: image-fdt: free old dtb reservations")
U-Boot now produces some nasty bogus error messages on Apple Silicon:

The issue here is that these memory regions have been reserved already
by the previous boot stage and have already been excluded from the
memory listed under the /memory node:

    Node 0x22568
        name: 'memory'
        device_type: 'memory'
        reg: 00000100.011e0000.00000003.d2a34000.00000103.d3c18000.00000000.00004000

These regions are listed under /reserved-memory since they are
referenced by other nodes in the device tree.

I suspect there are scenarios on other hardware platforms where this
will happen as well.  Can this be fixed?
