4188ea2aeb ARM: bcm283x: Define UART pinmuxing on board level
Until RPI 3 and Zero W the pl011 (uart0) was always on pin 14/15. So in
order to take care of them and other boards in the future,
we need to define UART pinmuxing on board level.

This work based on Eric Anholt's patch "ARM: bcm2385: Don't force pl011
onto pins 14/15." and Fabian Vogt's patch "ARM64: dts: bcm2837: assign
uart0 to BT and uart1 to pin headers".

As the alt3 group has no pins left drop it from &gpio.

00a33ec464 ARM: dts: bcm283x: Add dtsi for USB host mode
In case dr_mode isn't passed via DT, the dwc2 defaults to OTG mode.
But all Raspberry Pi boards here are designed only for host mode.
So fix this issue by providing a dtsi file which set the dr_mode
to host.

6a93792774 ARM: bcm2835: dt: Add the ethernet to the device trees
The hub and the ethernet in its port 1 are hardwired on the board.

Compared to the adapters that can be plugged into the USB ports, this
one has no serial EEPROM to store its MAC. Nevertheless, the Raspberry Pi
has the MAC address for this adapter in its ROM, accessible from its
firmware.

U-Boot can read out the address and set the local-mac-address property of the
node with "ethernet" alias. Let's add the node so that U-Boot can do its
business.

Model B rev2 and Model B+ entries were verified by me, the hierarchy and
pid/vid pair for the Version 2 was provided by Peter Chen. Original
Model B is a blind shot, though very likely correct.

80534f095f ARM: bcm2835: Add devicetree for bcm2836 and Raspberry Pi 2 B
The Pi 2 B ends up like a Pi 1 B+, with the same peripherals and
pinout, but the CPU and memory layout changed to use the 2836.
