mpc85xx: reserve upper 1MB of RAM for WS-AP3825i

Browse Source 
The bootpage for the second core is placed by U-Boot in the upper 128k
of syste-memory.

This could either be a reserved-area or deducted from the total
system-memory. As only the latter is parsed by the bootwrapper, reduce
the available system memory for linux in order to preserve the bootpage
from being overwritten.
