The qemu-rv use a small init code for M mode in kernel build. It is hard-coding and is difficult to change. Due to the fact, introduce a already mature SBI implement (e.g OpenSBI) to replace existing code is a better choice. This patch introduce some change for qemu-rv: 1. use SSTC to provide time interrupt in kernel build 2. remove uncessary M mode trap. For simplicity, this patch does not add support for booting nuttx for any core, but force boot core to start core 0 and let core 0 do the initialization.
