arm: allocate per-PCPU domheap pagetable pages
the domheap mappings are supposed to be per-PCPU. Therefore xen_pgtable
becomes a per-PCPU variable and we allocate and setup the page tables for each
secondary PCPU just before we tell it to come up.
Each secondary PCPU starts out on the boot page table but switches to its own
page tables ASAP.
The boot PCPU uses the boot pagetables as its own.
