mtd: rawnand: realtek: Make rtl_ecc_engine_ops const

The rtl_ecc_engine_ops structure is only used to provide a set of
callback functions and is never modified after initialization.
Mark it as const so it can be placed in the read-only section, which
improves safety and allows better compiler optimization.
