[U-Boot] [PATCH] mpc83xx: Define _end symbol

[Mario Six]

To support OF_EMBED, the MPC83xx architecture has to define the "_end"
symbol to correctly access the appended DT.

Fortunately, MPC8xx already defines the symbol, and the linker script is
quite similar to that of MPC83xx, so copy this approach for MPC83xx.
