The upstream branch might suffer rebases due to effort of pushing the
patches upstream. To avoid issues, let's have here the patches we need
for RPi 4 support.

We can do this because the kernel now includes a workaround for the DMA
issue.

This version includes a workaround for the usable DMA memory. It limits
the DMA to the first 1G.

We already do this for rpi3-64 and we will need it for rpi4-64 as well.
See 6c4de0b5fe44b8e661f1391ee8540a7f04d75315 for more details.

Currently, we use vc4-kms-v3d as the default overlay for VC4 but this
seems to break vc4 at runtime on RPi4. Change this to vc4-fkms-v3d for
now as this is the default Raspbian ons as well.

The official Raspbian with RPi4 support has an additional change for the
NVRAM WiFi configuration: boardflags3 value is changed from "0x48200100"
to "0x44200100". Without this change the interface never comes up. It is
confusing because the deb changelog doesn't say anything about it and
the repository upstream doesn't have this change. Asked for more info
here:
https://github.com/RPi-Distro/firmware-nonfree/issues/3
In the meanwhile we import this change. Also, we remove the .pc directory
which confuses the patch step.
