irqchip: Add RISC-V advanced PLIC driver for direct-mode
The RISC-V advanced interrupt architecture (AIA) specification defines
advanced platform-level interrupt controller (APLIC) which has two modes
of operation: 1) Direct mode and 2) MSI mode.
(For more details, refer https://github.com/riscv/riscv-aia)
In APLIC direct-mode, wired interrupts are forwared to CPUs (or HARTs)
as a local external interrupt.
Add a platform irqchip driver for the RISC-V APLIC direct-mode to
support RISC-V platforms having only wired interrupts.
