Add RISC-V cell-specific fields. Unlike ARM, for example, the PLIC doesn't support hardware injection of external IRQs. So we need to do it in software, sigh...
Prepare the fields that are needed for software injection. The irq_bitmap, just like on ARM, denotes physical IRQs that the cell is allowed to manage.
