drm/msm/dpu: fix the programming of INTF_CFG2_DATA_HCTL_EN
Currently INTF_CFG2_DATA_HCTL_EN is coupled with the enablement
of widebus but this is incorrect because we should be enabling
this bit independent of widebus except for cases where compression
is enabled in one pixel per clock mode.
Fix this by making the condition checks more explicit and enabling
INTF_CFG2_DATA_HCTL_EN for all other cases when supported by DPU.
Fixes: 3309a7563971 ("drm/msm/dpu: revise timing engine programming to support widebus feature")
