[U-Boot] [PATCH] 85xx: Fix memory test range on MPC8536DS

[Felix Radensky]

With current values of CONFIG_SYS_MEMTEST_START
and CONFIG_SYS_MEMTEST_END memory test hangs if
run without arguments. Set them to sane values,
so that all available 512MB of RAM excluding
exception vectors at the bottom and u-boot code
and stack at the top can be tested.
