The RISC-V Advanced Interrupt Architecture (AIA) specification introduces
the APLIC, which can serve as a new external interrupt controller to
replace the original Platform-Level Interrupt Controller (PLIC) or as a
device to convert wired interrupts into message-signaled interrupts
(MSIs) and forward them to the Incoming MSI Controller (IMSIC).
The APLIC driver supports both "direct delivery mode" and
"MSI delivery mode." Use the `CFG_RISCV_APLIC` flag to enable the
APLIC driver in "direct delivery mode," and use the
`CFG_RISCV_APLIC_MSI` flag to enable the APLIC driver in "MSI
delivery mode" when selecting `CFG_RISCV_IMSIC`.
APLIC initialization can be done through the device tree.
