Many uses of `azalia_set_bits` are used to toggle the reset bit. To
avoid having to repeat the register operations and the corresponding
comment, create two helpers with self-explanatory names. They will be
put to use in subsequent commits, with one change for each function.

Currently it's not possible to add multiple graphics drivers into
one coreboot image. This patch series will fix this issue by providing
a single API that multiple graphics drivers can use.
This is required for platforms that have two graphic cards, but
different graphic drivers, like Intel+Aspeed on server platforms or
Intel+Nvidia on consumer notebooks.
The goal is to remove duplicated fill_fb_framebuffer(), the advertisment
of multiple independent framebuffers in coreboot tables, and better
runtime/build time graphic configuration options.
Replace all duplications of fill_fb_framebuffer and provide a single one
in edid_fill_fb.c. Should not change the current behaviour as still only
one graphic driver can be active at time.

Add a NULL check and only skip setting the default operations
if `.ops` was set by a driver. It's fairly unlikely that some-
body adds a driver and forgets the `.ops` pointer. So this is
mostly to increase readability: Nobody should have to wonder
if we're missing a NULL-check.
The condition is moved out of the loop to reduce indentation
levels. Alternatively, we could jusk skip drivers that don't
have `.ops` set (i.e. continue the loop).

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.

The bus master bit is set at many places in coreboot's code, but the
reason for that is not quite clear. We examined not setting the
bus master bit whereever possible and tried booting without it,
which worked fine for internal PCI devices but not for PCIe. As a PCIe
device we used a Samsung M.2 NVMe SSD.
For security reasons, we would like to disable bus mastering where
possible. Depending on the device, bus mastering might get enabled
by the operating system (e.g. for iGPU) and it might be required for
some devices to work properly. However, the idea is to leave it disabled
and configure the IOMMU first before enabling it.
To have some sort of "backwards compatibility", add a method which
configures bus mastering based on an additional config option. Since
CB:42460 makes usage of this treewide, enable it by default to keep the
current behaviour for now.
Tested with Siemens/Chili, a Coffee Lake based platform.

Looks like no one really knows what this bit would be useful for, nor
when it would need to be set. Especially if coreboot is setting it even
on PCI *Express* bridges. Digging through git history, nearly all
instances of setting it on PCIe bridges comes from i82801gx, for which
no reason was given as to why this would be needed. The other instances
in Intel code seem to have been, unsurprisingly, copy-pasted.
Drop all uses of this definition and rename it to avoid confusion. The
negation in the name could trick people into setting this bit again.
