Now that all the drivers have been adjusted for it, let's bring in the
necessary device tree changes.
The VEC and PV3 are left out for now, since it will require a more specific
clock setup.

Depending on bcm2711's revision its emmc2 controller might have
different DMA constraints. Raspberry Pi 4's firmware will take care of
updating those, but only if a certain alias is found in the device tree.
So, move emmc2 into its own bus, so as not to pollute other devices with
dma-ranges changes and create the emmc2bus alias.
Based in Phil ELwell's downstream implementation.

This enables thermal for the BCM2711 (used on Raspberry Pi 4) by adding
the AVS monitor and a subnode for the thermal part.

With the introduction of the Raspberry Pi 4 we were forced to explicitly
configure CMA's location, since arm64 defaults it into the ZONE_DMA32
memory area, which is not good enough to perform DMA operations on that
device. To bypass this limitation a dedicated CMA DT node was created,
explicitly indicating the acceptable memory range and size.
That said, compatibility between boards is a must on the Raspberry Pi
ecosystem so this creates a common CMA DT node so as for DT overlays to
be able to update CMA's properties regardless of the board being used.

Raspberry Pi's firmware has a feature to select how much memory to
reserve for its GPU called 'gpu_mem'. The possible values go from 16MB
to 944MB, with a default of 64MB. This memory resides in the topmost
part of the lower 1GB memory area and grows bigger expanding towards the
begging of memory.
It turns out that with low 'gpu_mem' values (16MB and 32MB) the size of
the memory available to the system in the lower 1GB area can outgrow the
interconnect's dma-range as its size was selected based on the maximum
system memory available given the default gpu_mem configuration. This
makes that memory slice unavailable for DMA. And may cause nasty kernel
warnings if CMA happens to include it.
Change soc's dma-ranges to really reflect it's HW limitation, which is
being able to only DMA to the lower 1GB area.

arm64 places the CMA in ZONE_DMA32, which is not good enough for the
Raspberry Pi 4 since it contains peripherals that can only address the
first GB of memory. Explicitly place the CMA into that area.

This adds minimal support for the new Raspberry Pi 4 without the
fancy stuff like GENET, PCIe, xHCI, 40 bit DMA and V3D. The RPi 4 is
available in 3 different variants (1, 2 and 4 GB RAM), so leave the memory
size to zero and let the bootloader take care of it. The DWC2 is still
usable as peripheral via the USB-C port.
Other differences to the Raspberry Pi 3:
- additional GIC 400 Interrupt controller
- new thermal IP and HWRNG
- additional MMC interface (emmc2)
- additional UART, I2C, SPI and PWM interfaces
- clock stretching bug in I2C IP has been fixed
