This series does more improvements for supporting multiple PLIC
instances.

PATCH1 and PATCH4 are fixes whereas PATCH2 and PATCH3 help users
distinguish between multiple PLIC instances.

These patches are based up Linux-5.7-rc5 and can be found at
plic_imp_v1 branch at: https://github.com/avpatel/linux.git

To try this patches, we will need:
1. OpenSBI multi-PLIC and multi-CLINT support which can be found in
   multi_plic_clint_v1 branch at:
   https://github.com/avpatel/opensbi.git
2. QEMU RISC-V multi-socket support which can be found in
   riscv_multi_socket_v1 branch at:
   https://github.com/avpatel/qemu.git
