i386: modpost smpboot code warning fix

o Currently synchronize_tsc_ap() is of type __init. It is called by smp_callin() which is of type __cpuinit. So synchronize_tsc_ap() should be of type __cpuinit.

o Modpost generates warnings for i386 if CONFIG_RELOCATABLE=y and CONFIG_HOTPLUG_CPU=y

WARNING: vmlinux - Section mismatch: reference to .init.data: from .text between 'start_secondary' (at offset 0xc01164dc) and 'initialize_secondary'
WARNING: vmlinux - Section mismatch: reference to .init.data: from .text between 'start_secondary' (at offset 0xc01164e8) and 'initialize_secondary'

o tsc is of type __initdata. It should be of type __cpuinitdata.
