tcl/{board,target}: Add support for HiKey960
HiKey960 [1] is an octo-core development board manufactured by LeMaker and
based on the Hisilicon Kirin 960 SoC (aka Hi3660). It contains four Cortex
A53 and four Cortex A73 CPUs.
This patch adds basic support for the Hi3660 target and the HiKey960
board.
Tested with the Bus Blaster v3c adapter.
