irqchip/riscv-imsic: Add nr_guest_files in per-HART local config
Add nr_guest_files in per-HART local config to represent the number of
guest files available on a particular HART whereas the nr_guest_files
in the global config represents the number of guest files available
across all HARTs.
This allows KVM RISC-V to use nr_guest_files from per-HART local
config for asymmetric big.Little systems.
