ARM: dts: add Raspberry Pi Compute Module 3 and IO board
The Raspberry Pi Compute Module 3 (CM3) and the Raspberry Pi
Compute Module 3 Lite (CM3L) are SoMs which contains a BCM2837 processor,
1 GB RAM and a GPIO expander. The CM3 has a 4 GB eMMC, but on the CM3L
the eMMC is unpopulated and it's up to the user to connect their
own SD/MMC device. The dtsi file is designed to work for both modules.
There is also a matching carrier board which is called
Compute Module IO Board V3.
