drm/msm/disp/dpu1: add support to program fetch active in ctl path
A new register called CTL_FETCH_ACTIVE is introduced in
SC7280 family which is used to inform the HW about
the pipes which are active in the current ctl path.
This change adds support to program this register
based on the active pipes in the current composition.
