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.
