[PATCH 08/40] drm/msm/dp/dp_ctrl: Move 'tu' from the stack to the heap

'struct tu_algo_data' is huge ~400 Bytes.

Fixes the following W=1 kernel build warning(s):

drivers/gpu/drm/msm/dp/dp_ctrl.c: In function ‘_dp_ctrl_calc_tu.constprop’: drivers/gpu/drm/msm/dp/dp_ctrl.c:938:1: warning: the frame size of 1184 bytes is larger than 1024 bytes [-Wframe-larger-than=]
