drm/msm/dpu: use devres-managed allocation for HW blocks Use devm_kzalloc to create HW block structure. This allows us to remove corresponding kfree and drop all dpu_hw_*_destroy() functions as well as dpu_rm_destroy(), which becomes empty afterwards.

drm/msm/dpu: add setup_clk_force_ctrl() op to sspp & wb Starting from SM8550, the SSPP & WB clock controls are moved the SSPP and WB register range, as it's called "VBIF_CLK_SPLIT" downstream. Implement setup_clk_force_ctrl() only starting from major version 9 which corresponds to SM8550 MDSS.

drm/msm/dpu: use PINGPONG_NONE to unbind WB from PP Currently the driver passes the PINGPONG index to dpu_hw_wb_ops::bind_pingpong_blk() callback and uses separate boolean flag to tell whether WB should be bound or unbound. Simplify this by passing PINGPONG_NONE in case of unbinding and drop the flag completely.

drm/msm/dpu: simplify CDP programming Get rid of intermediatory configuration structure and defines. Pass the format and the enablement bit directly to the new helper. The WB_CDP_CNTL register ignores BIT(2), so we can write it for both SSPP and WB CDP settings.

drm/msm/dpu: Pass catalog pointers in RM to replace for-loop ID lookups The Resource Manager already iterates over all available blocks from the catalog, only to pass their ID to a dpu_hw_xxx_init() function which uses an _xxx_offset() helper to search for and find the exact same catalog pointer again to initialize the block with, fallible error handling and all. Instead, pass const pointers to the catalog entries directly to these _init functions and drop the for loops entirely, saving on both readability complexity and unnecessary cycles at boot.

drm/msm/dpu: Drop unused members from HW structs Some of these members were initialized while never read, while others were not even assigned any pointer value at all.
