drm/msm: make mdp5/dpu devices master components
The msm_mdss serves several roles at this moment. It provides IRQ domain
used by MDP5 and DPU drivers but it also serves as a component master
for both those usecases. MDP4 (which does not have separate MDSS device)
is the component master on it's own.
Remove this assymmetry and make both MDP5 and DPU component masters too.
This removes a need to care about drm/components from msm_mdss driver,
removes an mdss pointer from struct msm_drm_private and simplifies the
interface between mdp5/dpu and msm_drv.
