MIPS: relocate_code: fix barebox image memcpy() size
In this relocate_code() piece 'length' is greater than 'barebox_image_size':
#define MAX_BSS_SIZE SZ_1M
...
length = barebox_image_size + MAX_BSS_SIZE;
relocaddr = ALIGN_DOWN(ram_size - barebox_image_size, SZ_64K);
...
memcpy((void *)relocaddr, __image_start, length);
so 'ram_size' overflow occurs during memcpy().
