Revamp Intel microcode update code

- add GPLv2 + copyright header after talking to Ron
    - "bits" in struct microcode served no real purpose but
      getting its address taken. Hence drop it
    - use asm volatile instead of __asm__ volatile
    - drop superfluous wrmsr (that seems to be harmless but
      is still wrong) in read_microcode_rev
    - use u32 instead of unsigned int where appropriate
    - make code usable both in bootblock and in ramstage
    - drop ROMCC style print_debug statements
    - drop microcode update copy in Sandybridge bootblock
