Subject: x86/cpu: Use max host physical address if -cpu max option is applied

Git-commit: 5a140b255df922b98a165f0a2919602943c9062f
References: bsc#1188299

QEMU option -cpu max(max_features) means "Enables all features supported by
the accelerator in the current host", this looks true for all the features
except guest max physical address width, so add this patch to enable it.
