kernel: support large 64-bit pci membars, increase pc64 VMAPSIZE to 1TB
This makes vmap()/vunmap() take a vlong size argument,
and change the type of Pci.mem[].size to vlong as well.
Even if vmap() wont support large mappings, it is nice to
get the original unruncated value for error checking.
pc64 needs a bigger VMAP window, as system76 pangolin
puts the framebuffer at a physical address > 512GB.
