pci_cfgreg: Add a PCI domain argument to the low-level register API

This commit changes the API of pci_cfgreg(read|write) to add a domain
argument (referred to as a segment in ACPI parlance) (note that this
is not the same as a NUMA domain, but something PCI-specific). This
does not yet enable access to domains other than 0, but updates the
API to support domains.

Places that use hard-coded bus/slot/function addresses have been
updated to hardcode a domain of 0. A few places that have the PCI
domain (segment) available such as the acpi_pcib_acpi.c Host-PCI
bridge driver pass the PCI domain.

The hpt27xx(4) and hptnr(4) drivers fail to attach to a device not on
domain 0 since they provide APIs to their binary blobs that only
permit bus/slot/function addressing.

The x86 non-ACPI PCI bus drivers all hardcode a domain of 0 as they do
not support multiple domains.

Add basic support for ACPI. It splits out the nexus driver to two new
drivers, one for fdt, one for acpi. It then uses this to decide if it will
use fdt or acpi.

The GICv2 (interrupt controller) and Generic Timer drivers have been
updated to handle both cases.

As this is early code we still need FDT to find the kernel console, and
some parts are still missing, including PCI support.
