drm/amdkfd: add SPM support for SVM
When CPU is connected throug XGMI, it has coherent access to VRAM
resource. In this case that resource is taken from a table in the device
gmc aperture base. This resource is used along with the device type,
which could be DEVICE_PRIVATE or DEVICE_COHERENT to create the device page
map region.
Also, MIGRATE_VMA_SELECT_DEVICE_COHERENT flag is selected for coherent
type case during migration to device.
