ARM: dts: k2g: add support for Davinci SPI controller

K2G SoC has 4 SPI instances that are compatible with davinci_spi
controller(present on previous generation of Keystone2 devices). Add DT
nodes for the same. K2G EVM has a N25Q128A13 SPI NOR flash connected on
SPI-1. Add DT bindings for the same.
