drm/msm/mdss: generate MDSS data for MDP5 platforms

Browse source

Older (mdp5) platforms do not use per-SoC compatible strings. Instead
they use a single compat entry 'qcom,mdss'. To facilitate migrating
these platforms to the DPU driver provide a way to generate the MDSS /
UBWC data at runtime, when the DPU driver asks for it.

It is not possible to generate this data structure at the probe time,
since some platforms might not have MDP_CLK enabled, which makes reading
HW_REV register useless and prone to possible crashes.
