configs/spike_riscv64: bump kernel to 6.1.14 Linux Kernel 6.1 now being officially promoted to be a LTS, this commit bump the kernel version of this defconfig to 6.1.14. A Kernel config fragment "linux.fragment" is now needed as the kernel no longer enable SBI v0.1 support and the earlycon RISC-V SBI in its riscv arch defconfig. See [1] [2]. The Spike riscv-isa-sim was updated upstream accordingly [3]. In order to keep a smooth transition, this kernel config fragment re-enable those options to make sure this kernel will work with both old Spike versions (not including commit [3] like the v1.1.0 currently included in Buildroot), and newer versions. This commit was also successfully tested with riscv-isa-sim at commit 0d1a48c0c0.
