HVMlite guests (to be introduced in subsequent patches) share most

Whoa, I'm lost, its hard for me to tell what exactly stayed and what
got pulled into a helper, etc. Is there a possibility to split this
patch in 2 somehow to make the actual functional changes easier to
read? There are too many changes here and I just can't tell easily
what's going on.

The only real changes that this patch introduces is it reorders some of the operations that used to be in xen_start_kernel(). This is done so that in the next patch when we add hvmlite we can easily put those specific to PV(H) inside 'if (!xen_hvm_domain())'. I probably should have said so in the commit message.

It is indeed difficult to review but I don't see how I can split this. Even if I just moved it (without reordering) it would still be hard to read.
