ACPICA: MADT: Add RISC-V external interrupt controllers
ACPICA commit 8c048cee4ea7b9ded8db3e1b3b9c14e21e084a2c
This adds 3 different external interrupt controller
definitions in MADT for RISC-V.
1) RISC-V PLIC is a platform interrupt controller for
handling wired interrupt in a RISC-V systems.
2) RISC-V IMSIC is MSI interrupt controller to
support MSI interrupts.
3) RISC-V APLIC has dual functionality. First it can
act like PLIC and direct all wired interrupts to
the CPU which doesn't have MSI controller. Second,
when the CPU has MSI controller (IMSIC), it will
act as a converter from wired interrupts to MSI.
Update the existing RINTC structure also to support
these external interrupt controllers.
This codefirst ECR is approved by UEFI forum and will
be part of next ACPI spec version.
