ARM: dts: keystone-evm: add spi nor flash support
k2hk, k2e, k2l EVM board have the same Micron N25Q128A11 SPI NOR Flash installed on SPI0 bus. The NOR Flash is splitted on two partistions: partition@0 label = "u-boot-spl"; reg = <0x0 0x80000>; partition@1 label = "misc"; reg = <0x80000 0xf80000>; Hence, add SPI NOR Flash nodes to all k2hk, k2e, k2l EVM boards.
