x86: remove wrong setting about CONSTANT_TSC for intel cpu

early_init_intel() on 64-bit is introduced by

      x86: move X86_FEATURE_CONSTANT_TSC into early cpu feature detection

sets CONSTANT_TSC for intel cpus - but it is already set in init_intel().

don't need to set that two times in early_init_intel() and init_intel().
this patch removes the init_intel() one.
