amdgpu/addrlib: Let Kaveri go general stereo right eye offset padding path

Kaveri (2-pipe) macro tiling mode table was initially set to all
4-aspect-ratio so the swizzling path did not work for it and then we
chose to pad the offset. We now discover the root cause is that if
ratio > 2, the swizzling path does not work. So we can safely use the
same path for Kaveri.
