    x86/debug: Remove ancient debugging noise from boot log when starting cpus

    Printing the "start_ip" for every secondary cpu is very noisy on
    a large system - and doesn't add any value. Drop this message.

    Console log before:

    Booting Node 0, Processors #1
    smpboot cpu 1: start_ip = 96000
    #2
    smpboot cpu 2: start_ip = 96000
    #3
    smpboot cpu 3: start_ip = 96000
    #4
    smpboot cpu 4: start_ip = 96000
    ...
    #31
    smpboot cpu 31: start_ip = 96000
    Brought up 32 CPUs

    Console log after:

    Booting Node 0, Processors #1 #2 #3 #4 #5 #6 #7 Ok.
    Booting Node 1, Processors #8 #9 #10 #11 #12 #13 #14 #15 Ok.
    Booting Node 0, Processors #16 #17 #18 #19 #20 #21 #22 #23 Ok.
    Booting Node 1, Processors #24 #25 #26 #27 #28 #29 #30
    #31 Brought up 32 CPUs
