hw/intc: Add RISC-V AIA APLIC device emulation

Browse source 
The RISC-V AIA (Advanced Interrupt Architecture) defines a new
interrupt controller for wired interrupts called APLIC (Advanced
Platform Level Interrupt Controller). The APLIC is capabable of
forwarding wired interupts to RISC-V HARTs directly or as MSIs
(Message Signaled Interupts).

This patch adds device emulation for RISC-V AIA APLIC.
