Keystone2 Edison (K2E) is a Quad Cortex A15 based SoC with
1 DSP. It has standard peripherals such as i2c, spi, uart, timer,
pcie, etc similar to k2hk, but without wireless hardwares. This
patch add support for k2 Edison SoC and EVM. This re-uses the common
keystone.dtsi to include common bindings across the various k2
devices.
