Series RISC-V: ACPI: Add external interrupt controller support | expand

Commit Message

Sunil V L April 15, 2024, 5:01 p.m. UTC 
On RISC-V platforms, apart from root interrupt controllers (which
provide local interrupts and IPI), other interrupt controllers in the
hierarchy are probed late. Enable this CONFIG option for RISC-V ACPI
based platforms.
