arch/x86,cpu/x86/mp_init: Switch cpu_info index type to size_t 

The alignment for `struct cpu_info` is wrong on x86_64. c_start.S uses
the `push` instruction when setting up the cpu_info struct. This
instruction will push 8 bytes but `unsigned int` is 4 bytes. By making
it a `size_t` we get the correct size for both x86_32 and x86_64.
