x86: Reserve setup_data ranges late after parsing memmap cmdline
Currently e820_reserve_setup_data() is called before parsing early params, it works in normal case. But for memmap=exactmap, the final memory ranges are created after parsing memmap= cmdline params, so the previous e820_reserve_setup_data() has no effect. For example, setup_data ranges will still be marked as normal system ram, thus when later sysfs driver ioremap them kernel will warn about mapping normal ram. This patch fix it by moving the e820_reserve_setup_data() callback after parsing early params so they can be set as reserved ranges and later ioremap will be fine with it.
