coreboot: rename from NeKernel firmware, refactor symbols to `cb_`, update docs
This patch completes a major renaming and cleanup of the firmware codebase:
- Rename project from "NeKernel Firmware" to "CoreBoot" in README and comments.
- Replace all `mp_`-prefixed symbols with `cb_` to reflect the new naming scheme.
- Remove obsolete SPECIFICATION.TXT and replace with SPECIFICATION_FIRMWARE.md.
- Update memory-mapped I/O helpers, TLB init, and platform-specific code to match `cb_*` naming.
- Refactor low-level UART, panic, PCI-tree, partition map, and context setup to use unified `cb_` API.
- Adjust linker scripts and boot vectors for ARM64, PPC64, and RV64 targets accordingly.
- Add Doxygen documentation note to README.
This change is part of an ongoing effort to rebrand and unify the firmware interface, improve naming clarity, and better align with platform-specific toolchains.
