target/arm: Provide cpu property for controling FEAT_LPA2
There is a Linux kernel bug present until v5.12 that prevents booting with FEAT_LPA2 enabled. As a workaround for TCG, allow the feature to be disabled from -cpu max. Since this kernel bug is present in the Fedora 31 image that we test in avocado, disable lpa2 on the command-line.
