MIPS: Sibyte: Platform: Add load address for CONFIG_SIBYTE_LITTLESUR

Fixes the following build problem:
mips-linux-gnu-ld:arch/mips/kernel/vmlinux.lds:253: syntax error

because VMLINUX_LOAD_ADDRESS was an empty string for that platform
so the vmlinux.lds.S created an invalid section entry on line 50.
