irqchip: riscv-imsic: Fixup riscv_ipi_set_virq_range() conflict

There was a semantic conflict between 21a8f8a0 ("irqchip: Add RISC-V
incoming MSI controller early driver") and dc892fb4 ("riscv: Use
IPIs for remote cache/TLB flushes by default") due to an API change.
This manifests as a build failure post-merge.
