lib: Add dynamic registration of SBI extensions This patch extends our SBI ecall implementation to allow dynamic registration of various SBI extensions. Using this dynamic registration we can break-up SBI ecall implementation into multiple files and even register experimental/custom SBI extensions from platform code.
