File target-i386-enable-monitor-and-ucode-rev.patch of Package qemu.20375

Subject: target/i386: enable monitor and ucode revision with -cpu max

Git-commit: be02cda3afde60d219786e23c3f8edb53aec8e17
References: jsc#SLE-17785

These two features were incorrectly tied to host_cpuid_required rather than
cpu->max_features.  As a result, -cpu max was not enabling either MONITOR
features or ucode revision.
