Zide Chen 2b35c07857 hv: do EPT mapping only for physical memory backed GPA on pre-launched VMs ...

Currently for pre-launched VMs, HV intends to do EPT mapping for all GPA
space, which implies that it wastes HPA to back PCI hole and other vE820
entries that are not backed by physical memory.

This patch solves this issue and fixes ve820 entries whose length is not
aligned to 4K, and changes the lowmem entry's start GPA from 1MB to 2MB.
