drm/tests: Add a few tests around drm_fixed.h
While working on the CTM implementation of VKMS I had to ascertain
myself of a few assumptions. One of those is whether drm_fixed.h
treats its numbers using signed-magnitude or twos-complement. It is
twos-complement.
In order to make someone else's day easier I am adding the
drm_test_int2fixp test that validates the above assumption.
I am also adding a test for the new sm2fixp function that converts
from a signed-magnitude fixed point to the twos-complement fixed
point.
