x86: remove depends on X86_32 from PARAVIRT & PARAVIRT_GUEST

Browse Source 
With this, the paravirt_ops code can be enabled on x86_64 also.

Each guest implementation (Xen, VMI, lguest) now depends on X86_32. The
dependencies can be dropped for each one when they start to support
x86_64.

This changes the kernel so it can modify itself when it is run
under a hypervisor, potentially improving performance significantly
