microblaze: Do not copy reset vectors/manual reset vector setup
Reset vector can be setup by bootloader and kernel doens't need to touch it. If you require to setup reset vector, please use CONFIG_MANUAL_RESET_VECTOR throught menuconfig. It is not possible to setup address 0x0 as reset address because make no sense to set it up at all.
