Changbin Du d480b28a41 drm/i915/gvt: Fix aperture read/write emulation when enable x-no-mmap=on 
When add 'x-no-mmap=on' for vfio-pci option, aperture access in guest
is emulated. But the vgpu_aperture_rw() function take wrong offset when
do memcpy, since vgpu->gm.aperture_va is not the base of entire aperture.
This mistake cause GPU command in guest get lost and so the seqno is not
updated in engine HWSP.

This patch fix this, and it also move the emulation code to kvmgt.
Because only vfio need to emulate it. Put aperture rw to MMIO emulation
path breaks assumptions in xengt.

v2: Remove PAGE_ALIGN for size (zhenyu)

Fixes: f090a00df9 ("drm/i915/gvt: Add emulation for BAR2 (aperture) with normal file RW approach")
