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.
