Current, PLIC driver can support only 1 PLIC on the board. However,
there can be multiple PLICs present on a two socket systems in RISC-V.

Modify the driver so that each PLIC handler can have a information
about individual PLIC registers and an irqdomain associated with it.

Tested on two socket RISC-V system based on VCU118 FPGA connected via
OmniXtend protocol.

This patch is rebased on top of 5.6-rc2 and following plic fix from
hotplug series.

https://lkml.org/lkml/2020/2/20/1220

How do you want this to be merged? I haven't really followed the hotplug
series, but given that this is a pretty simple patch, I'd rather have things
based the other way around so that it can be merged independently.

Thanks,

M.
