To enable DVFS, DRAM driver needs to access four different
regulators that SoC can't access directly and need board-specific
implementations.
To support that we need to define the getter and setter APIs for
those regulators.

This driver is for the root port device and needs to reference the
parent device for its ACPI scope. Similarly for the debug output it
needs to use the parent device, and fall back to the chip name if
config->desc is not provided in the devicetree.
The UID property is removed. This value is not the same as the port
number; according to some docs it should be unique but it is not fully
clear what it should be tied to. Regardless, it is not used by the
Thunderbolt driver in the kernel.
I also renamed some functions/structures to be clear that this is just
an ACPI driver for the PCIe root port and not a driver for the root port
itself. As part of this I removed the PCI based resource operations and
the scan bus function since this device does not have children itself.
Finally I added a detailed comment with an example describing what the
driver is for and what properties it generates.

This change allows a generic device to be described in the devicetree
under a PCI device, such as a root port.
Previously any device under a PCI device was expected to also be a PCI
device and that does not allow for a virtual/generic device to be
present, for example to provide ACPI properties for a root port.
The changes are:
- Ignore non-PCI devices found under a PCI device when scanning and do
not print an error for each devfn scanned.
- Don't treat non-PCI devices as leftover and remove them, instead
enable them as a static device.
- Don't attempt to configure a static device in the tree that is not a
PCIe device type.
With these changes it is now possible to have a generic device under a
PCI device, for example in a USB4/TBT root port (PCIe hotplug device)
this generic device will add ACPI properties for the PCIe tunnel routed
to the external port:
device pci 07.0 on
chip soc/intel/common/block/pcie
device generic 0 on end
end
end
TEST=boot on volteer with the USB4 root port devices in chipset.cb and
ensure they are enabled properly and there are no errors printed in the
coreboot log, and that the device properties are created in the SSDT.
