VHE: Update cpu code to allow for el0 partition execution To run a el0 partitions vcpu the following changes are required: 1) HCR_EL2.TGE bit always needs to be set. 2) SPSR needs to be set to EL0t mode. 3) ttbr0_el2 needs to switched to the appropriate table. To do this a new vcpu field for ttbr0_el2 is added. For normal VM's, ttbr0_el2 is the same as the hypervisor page tables and for el0 partition's, the appropriate page table and asid are used. ttbr0_el2 is now loaded on every exit from el2.
