Alper Nebi Yasak 4e00e6291a arch/io.h: Add port I/O functions to other architectures 
The QEMU Bochs display driver and the QEMU Firmware Configuration
interface code (in the qemu-i440fx mainboard dir) were written for x86.
These devices are available in QEMU VMs of other architectures as well,
so we want to port them to be independent from x86.

The main problem is that the drivers use x86 port I/O functions to
communicate with devices over PCI I/O space. These are currently not
available for ARM* and RISC-V, although it is often still possible to
access PCI I/O ports over MMIO through a translator.

Add implementations of port I/O functions that work with PCI I/O space
on these architectures as well, assuming there is such a translator at a
known address configured at build-time.
