Message:

Implement support for HiKey 960

Initial support for the 96Boards HiKey 960 board.

• The kernel identity mapping has been extended to 4 GiB. The initial bootstrap mapping maps 3 GiB as nornal memory and the next 1 GiB as device memory to support early UART debugging output.

• The istate_t has been padded in order to preserve the stack pointer alignment invariant.

The current implementation is limited to UP and UART input/output.
