ppc/ppc405: Change kernel load address
The default addresses to load the kernel, fdt, initrd of AMCC boards
in U-Boot v2015.10 are :
"kernel_addr_r=1000000\0"
"fdt_addr_r=1800000\0"
"ramdisk_addr_r=1900000\0"
The taihu is one of these boards, the ref405ep is not but we don't
have much information on it and both boards have a very similar
address space layout.
Also, if loaded at address 0, U-Boot will partially overwrite the
uImage because of a bug in get_ram_size() (U-Boot v2015.10) not
restoring properly the probed RAM contents and because the exception
vectors are installed in the same range. Finally, a gzipped kernel
image will be uncompressed at 0x0. These are all good reasons for not
mappping a kernel image at this address.
Change the kernel load address to match U-Boot expectations and fix
loading.
