[IA64] use of max_addr= & command line
Use 'max_addr' option to limit the amount of physical memory. The
default is 4G (the same as the previous hard limit). The hard-coded
limit is removed. dom0_command_line now contains the cmdline for
dom0 linux. saved_command_line now contains the cmdline for Xen (it
is used in Xen).
