mpc85xx: fix address config for ws-ap3825i

mpc85xx: fix address config for ws-ap3825i

In commit 6a8b83159389 ("mpc85xx: p1010: change wrapper address of
simple image devices"), we adjusted the wrapper address in the recipe
code for all mpc85xx simpleimage devices, including the Extreme
Networks WS-AP3825i. However, we did not also adjust the
KERNEL_LOADADDR and KERNEL_ENTRY config values for this board. This
broke the simpleimage wrapper loader, causing GitHub issue #15237.

Adjust those config values so we go back to pointing at the right
address. We don't exactly need the memory, but it's also not exactly a
punishment in this case.

Run-tested on a ws-ap3825i.

Fixes: commit 6a8b83159389 ("mpc85xx: p1010: change wrapper address of
simple image devices")
