With this patch removing SWIOTLB_FORCE from four places in
kernel code, there are no remaining places where it is set.
The test of SWIOTLB_FORCE could be removed from
swiotlb_init_remap(), and its definition could be deleted
from include/linux/swiotlb.h.

That's great! I think it shows this is the right approach!
