x86: reserve end-of-conventional-memory to 1MB, 64-bit, use paravirt_enabled
Jeremy Fitzhardinge pointed out that looking at the boot_params struct to determine if the system is running in a paravirtual environment is not reliable for the Xen case, currently. He also points out that there already exists a function to determine if the system is running in a paravirtual environment. So let's use that instead. This gets rid of the preprocessor test too.
