[PATCH] ARM: dts: bcm2835: Enable 3D rendering through V3D

[Maíra Canal]

RPi 0-3 is packed with a GPU that provides 3D rendering capabilities to
the RPi. Currently, the downstream kernel uses an overlay to enable the
GPU and use GPU hardware acceleration. When deploying a mainline kernel
to the RPi 0-3, we end up without any GPU hardware acceleration
(essentially, we can't use the OpenGL driver).

Therefore, enable the V3D core for the RPi 0-3 in the mainline kernel.

I decided to add the status property to the `bcm2835-common.dtsi`, but
there are two other options:

1. To add the status property to the `bcm2835-rpi-common.dtsi` file
2. To add the status property to each individual RPi model, e.g.
`bcm2837-rpi-3-b.dts`.

Let me know which option is more suitable, and if `bcm2835-common.dtsi`
is not the best option, I can send a v2.

Best Regards,
