arm64: Add Juno board device tree.
This adds support for ARM's Juno development board (rev 0). It enables most of the board peripherals: UART, I2C, USB, MMC and 100Mb ethernet. There is no support at the moment for clock setting and HDLCD driver which depends on it. Signed-off-by: Liviu Dudau <Liviu.Dudau@arm.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
