hv:move down the structure intr_source

Now the structures(union source & struct intr_source) are defined
in ptdev.h,they are used in vtd.c and assign.c,
vtd is the hardware layer and ptdev is the upper-layer module
from the modularization perspective, this patch move down
these structures to avoid reversed dependency.
