x86 setup: initialize LDTR and TR to make life easier to Intel VT
Intel VT doesn't like to engage when the protected-mode state isn't fully initialized. Make life easier for it by initializing LDTR (to null) and TR (to a dummy hunk of low memory which will never actually be touched.) Signed-off-by: H.
