[U-Boot] [PATCH] ppc4xx: Don't fixup NOR flash node size on Ebony

[Stefan Roese]

Don't update size in "reg" property of NOR FLASH device tree nodes.
This leads to a problem with this NOR flash setup, where
chip-select 0 is connected to 512KiB SRAM *and* 512KiB NOR flash.
And with this fixup-code, the size of the NOR flash node is changed
from 512KiB to 1MiB which leads to a crash in the Linux MTD driver.
