Pull RISC-V updates from Palmer Dabbelt:
- Enabling the FPU is now a static_key
- Improvements to the Svpbmt support
- CPU topology bindings for a handful of systems
- Support for systems with 64-bit hart IDs
- Many settings have been enabled in the defconfig, including both
support for the StarFive systems and many of the Docker requirements
There are also a handful of cleanups and improvements, as usual.
