🎀 ARGUMENTS 🎀

• node — the fdt node of the initialized region, bestie 🌟
• uname — the name of the reserved memory node 💅
• base — the base address of the reserved memory region 📍
• size — the size of the reserved memory region 📏

okay so literally: this function calls the region-specific initialization function for a reserved memory region, then it saves all the region-specific data to the reserved_mem array so of_reserved_mem_lookup can find it. that's the whole vibe ✨ no cap.
