Michal Orzel 1b9d4ec26b xen/arm64: Fix incorrect DIRECTMAP_SIZE calculation ...

The direct mapped area occupies L0 slots from 256 to 265 included
(i.e. 10 slots), resulting in 5TB (512GB * 10) of virtual address space.
However, due to incorrect slot subtraction (we take 9 slots into account)
we set DIRECTMAP_SIZE to 4.5TB instead. Fix it.

Note that we only support up to 2TB of physical memory so this is
a latent issue.
