k2hk: add support for k2hk SOC and EVM
k2hk EVM is based on Texas Instruments Keystone2 Hawking/Kepler
SoC. Keystone2 SoC has ARM v7 Cortex-A15 MPCore processor. Please
refer the ti/k2hk_evm/README for details on the board, build and other
information.
This patch add support for keystone architecture and k2hk evm.
