[PULL 03/31] x86/cpu: Use max host physical address if -cpu max option is applied

[Paolo Bonzini]

From: Yang Weijiang <weijiang.yang@intel.com>

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.
