hw/riscv: virt: Fix interrupt parent for dynamic platform devices

When both APLIC and IMSIC are present in virt machine, the APLIC should
be used as parent interrupt controller for dynamic platform devices.

In case of  multiple sockets, we should prefer interrupt controller of
socket0 for dynamic platform devices.

Fixes: 3029fab643 ("hw/riscv: virt: Add support for generating
platform FDT entries")
