[v3,00/15] Raspberry PI 4 V3D enablement

This series attempts to enable V3D on BCM2711, the SoC available on the
Raspberry Pi 4 family of boards.

Due to the lack of documentation some things are taken as it from
testing/downstream implementation[1], which I'm hilighting here:

- It's not clear that the following is 100% true, maybe someone can confirm:

	"In BCM2711 the new ARGON ASB took over V3D. The old ASB is still
	present with the ISP and H264 bits, and V3D is in the same place in the
	new ASB as the old one."

- Patch #9 ("soc: bcm: bcm2835-power: Bypass power_on/off() calls"), I
  took as is from the downstream implementation, I can't really provide
  an exact explanation on what changed HW wise.

- Ultimately, I need confirmation from the Broadcom folks that they are alright
  with patch #11 ("drm/v3d: Get rid of pm code")

With all this, I get a more or less stable experience using mesa 20.3.4 and
X11/Gnome.

Regards,
Nicolas
