target-i386: Remove icc_bridge parameter from cpu_x86_create()

Instead of passing icc_bridge from the PC initialization code to
cpu_x86_create(), make the PC initialization code attach the CPU to
icc_bridge.

The only difference here is that icc_bridge attachment will now be done
after x86_cpu_parse_featurestr() is called. But this shouldn't make any
difference, as property setters shouldn't depend on icc_bridge.
