These patches coninue work started by AngeloGioacchino Del Regno in the
previous cycle by further decoupling and dissecting MDSS and MDP drivers
probe/binding paths.

This removes code duplication between MDP5 and DPU1 MDSS drivers, by
merging them and moving to the top level.

This patchset depends on the patches 1 and 2 from [1]

Changes since v2:
 - Rebased on top of current msm/msm-next(-staging)
 - Allow disabling MDP4/MDP5/DPU/HDMI components (like we do for DP and
   DSI)
 - Made mdp5_mdss_parse_clock() static
 - Changed mdp5 to is_mdp5 argument in several functions
 - Dropped boolean device data from the mdss driver
 - Reworked error handling in msm_pdev_probe()
 - Removed unused header inclusion
 - Dropped __init/__exit from function prototypes

Changes since v1:
 - Rebased on top of [2] and [1]
