ARM: dts: bcm283x: Move the BCM2837 DT contents from arm64 to arm. BCM2837 is somewhat unusual in that we build its DT on both arm32 and arm64. Most devices are being run in arm32 mode. Having the body of the DT for 2837 separate from 2835/6 has been a source of pain, as we often need to make changes that span both directories simultaneously (for example, the thermal changes for 4.13, or anything that changes the name of a node referenced by '&' from board files). Other changes are made more complicated than they need to be, such as the SDHOST enabling, because we have to split a single logical change into a 283[56] half and a 2837 half. To fix this, make the stub board include file live in arm64 instead of arm32, and keep all of BCM283x's contents in arm32. From here on, our changes to DT contents can be submitted through a single tree. Signed-off-by: Eric Anholt <eric@anholt.net> Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>

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".
