target-ppc: always load kernel to KERNEL_LOAD_ADDR
Linux changed its physical address location in the elf header from 0xc0000000 to 0 on 2.6.25, causing later kernels to fail booting with the -kernel option. This patch assures that the lowest segment in the elf binary is loaded to KERNEL_LOAD_ADDR, which is where the firmware expects it.
