drm/vc4: Fix X/Y positioning of planes using T_TILES modifier

Browse source

X/Y positioning of T-format buffers is quite tricky and the current
implementation was failing to position a plane using this format
correctly when the CRTC X, Y or both X and Y offsets were negative.
It was also failing when the SRC X/Y offsets were != 0.
