[Skiboot] [PATCH 1/2] external/mambo: Populate kernel-base-address in the DT

[Russell Currey]

skiboot.tcl defines PAYLOAD_ADDR as 0x20000000, which is the default in
skiboot.  This is also the default in skiboot unless kernel-base-address
is set in the device tree.

If you change PAYLOAD_ADDR to something else for mambo, skiboot won't
see it because it doesn't set that DT property, so fix it so that it does.
