x86: detect scattered cpuid features earlier
commit 1dedefd1a066a795a87afca9c0236e1a94de9bf6 upstream.
Some extra CPU features such as ARAT is needed in early boot so
that x86_init function pointers can be set up properly.
http://lkml.org/lkml/2010/5/18/519
At start_kernel() level, this patch moves init_scattered_cpuid_features()
from check_bugs() to setup_arch() -> early_cpu_init() which is earlier than
platform specific x86_init layer setup. Suggested by HPA.
