x86: move X86_FEATURE_CONSTANT_TSC into early cpu feature detection
set CONSTANT_TSC for intel cpus
but it already set in init_intel
don't need to set that two times in early_init_intel() and init_intel. this
patch remove one.
also fix error in early_init_intel and reference about x86_capality, because it
is array already.., prevent possible data corruption...
this should be applied for 2.6.25
