plat/arm/board/sgi: Add board support for SGI-575 platform
SGI-575 consists of two clusters of four Cortex-A75 CPU's each.
The FVP for this platform does not support system suspend and
resume functionality as there is no wakeup source supported.
So all the system suspend and resume related tests are skipped.
