The upstreamed Unicam driver uses a dt property to denote how many
lanes are supported by the receiver peripheral, independent of
the number of lanes that the sensor wants to use. It also doesn't
check the remote endpoint config for the number of lanes as that
isn't the accepted way of doing things.

Update the base DT for the brcm,num-data-lanes property, and the
overlays to define the desired number of lanes at both ends of
the link.

Add device tree nodes for Bluetooth on supported Raspberry Pi boards.
It's disabled by default and can be enabled by `krnbt=on` dtparam. It's
an alternative way of configuring Bluetooth, as compared to hciattach or
btattach. When the dtparam is enabled, the Bluetooth driver is probed
automatically and doesn't require any additional bring-up scripts.

Note that Raspberry Pi 3 B rev 1.2 doesn't have the required hardware
flow control pins of UART0 connected to the Bluetooth module, so the
user should decrease the baudrate by passing `krnbt_baudrate=921600`
dtparam to make it more stable. It resembles the behavior of the btuart
script from Raspbian.

The miniuart-bt overlay was modified to support Bluetooth probing with
device tree, too. It's disabled by default and can be enabled by
`krnbt=on` parameter of the miniuart-bt overlay.

The next patch adds a device tree overlay for Bluetooth. The Bluetooth
device node is a child of uart0 (pl011). The children of pl011 are not
registered as platform devices by of_platform_bus_create, because they
fall into `of_device_is_compatible(bus, "arm,primecell")` check. These
children are registered by of_serdev_register_devices, called through
this chain of calls:

  - uart_add_one_port (drivers/tty/serial/amba-pl011.c)
  - tty_port_register_device_attr_serdev
  - serdev_tty_port_register
  - serdev_controller_add
  - of_serdev_register_devices

serdev_tty_port_register depends on CONFIG_SERIAL_DEV_CTRL_TTYPORT,
which in turn depends on CONFIG_SERIAL_DEV_BUS=y. This patch modifies
the defconfigs of Raspberry Pi devices to set these options and allow
to bind drivers to subnodes of UART devices that can be added by device
tree overlays.

The i2c-gpio driver expects to use a GPIO in open-drain mode. Failure
to configure it in that way causes alarming warnings in the kernel log.
The BCM283x and BCM2711 GPIO blocks don't support open-drain mode, but
gpiolib can emulate it in software if configured correctly.

Silence the warning by declaring the GPIOs as requiring open-drain
mode, trusting gpiolib to manage the emulation. The previous
incarnation of this patch took the other approach of telling the
i2c-gpio driver that the GPIOs were configured for open-drain, but
this had the effect of disabling the emulation. In some cases this
appears to work, but examining the waveforms as analogue voltages
shows contention, the success or failure depending on drive strengths.

Things don't work too well when both the vc4 driver and the firmware
driver are trying to control the same audio output:

[  763.569406] bcm2835_audio bcm2835_audio: vchi message timeout, msg=5

Hence, when the vc4 HDMI driver is used, let it control audio. This is done
by introducing a new device tree property to the audio node, and
extending the vc4-kms-v3d overlays to set it appropriately.
