[PATCH 0/3] Improvements for ARC simulation platform

[Alexey Brodkin]

Along with some clean-up we make 2 important changes:
 1. Switch to more standard 16550 UART instead of our custom "ARC UART".
    This paves the way for using this board in QEMU.

 2. Now when nSIM virtual board is usable in QEMU we add support of Virtio
    NIC & block device similarly as we did that in the Linux kernel [1].

  ARC: nSIM: switch from ARC UART to DW UART
  ARC: nsim_{700|700be|hs38be}_defconfigs: Disable networking
  ARC: nsim_hs38: Add support of Virtio NET & BLK
