x86: fix numaq_tsc_disable calling

Browse Source 
got this on a test-system:

 calling  numaq_tsc_disable+0x0/0x39
 NUMAQ: disabling TSC
 initcall numaq_tsc_disable+0x0/0x39 returned 0 after 0 msecs

that's because we should not be using arch_initcall to call numaq_tsc_disable.

need to call it in setup_arch before time_init()/tsc_init()
and call it in init_intel() to make the cpu feature bits right.
