target-i386: Publish advised value of MSR_IA32_FEATURE_CONTROL via fw_cfg
It's a prerequisite that certain bits of MSR_IA32_FEATURE_CONTROL should be set before some features (e.g. VMX and LMCE) can be used, which is usually done by the firmware. This patch adds a fw_cfg file "etc/msr_feature_control" which contains the advised value of MSR_IA32_FEATURE_CONTROL and can be used by guest firmware (e.g. SeaBIOS).
