cpu/intel/model_206ax: Write MSRs in scope package only once

Write MSRs that are in scope package only once by checking for the BSP
bit. While this improves performance a bit it also has the benefit
that registers can be safely locked down without the need for
semaphores.

TEST: Lenovo X220 still boots.
