This series improves the ISA extension ONE_REG interface in following ways:
1) Move ONE_REG related code to dedicated source file
2) Allow multiple ISA extensions to be enabled/disabled in one ioctl
3) Add more ISA extensions to the ONE_REG interface

The series has following dependencies:
1) PATCH6 depends on
https://lore.kernel.org/linux-riscv/20230712084134.1648008-1-sameo@rivosinc.com/
2) PATCH7 depends on
https://lore.kernel.org/linux-riscv/20230711153743.1970625-1-heiko@sntech.de/

The PATCH1 to PATCH5 of this series don't depend on any patches.

These patches can also be found in the riscv_kvm_onereg_imp_v1 branch at:
https://github.com/avpatel/linux.git

I have queued PATCH1 to PATCH5 for Linux-6.6 so that other in-flight
patches can be rebased on the riscv_kvm_queue.

The PATCH6 and PATCH7 will have to wait until required dependencies
are merged in arch/riscv.

Thanks,
Anup
