From: Murali Karicheri <m-karicheri2 at ti.com>
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 at 0
label = "u-boot-spl";
reg = <0x0 0x80000>;
partition at 1
label = "misc";
reg = <0x80000 0xf80000>;
Hence, add SPI NOR Flash nodes to all k2hk, k2e, k2l EVM boards.
