Introduce a QEMU device model for ASPEED's One-Time Programmable (OTP)
memory.
This model simulates a word-addressable OTP region used for secure
fuse storage. The OTP memory can operate with an internal memory
buffer.
The OTP model provides a memory-like interface through a dedicated
AddressSpace, allowing other device models (e.g., SBC) to issue
transactions as if accessing a memory-mapped region.
