Remove the 32KB VHPT section from the kernel image. We don't really
use it because we allocate a VHPT based on the size of the physical
memory and even if the allocated VHPT is 32KB, we don't use the in-
image section for it. Since the VHPT must be naturally aligned, we
save 48K on average (due to alignment).
Consequently, we start off with the VHPT disabled (it is assumed
the VHPT is disabled because the EFI loader runs without memory
address translation and thus has no need to setup the VHPT). It's
probably a good idea to explicitly disable the VHPT if we make the
use of the VHPT optional.
