[PATCH 2/2] arm64: dts: arm: add corstone1000 device tree

Corstone1000 is a platform from arm, which includes pre
verified Corstone SSE710 sub-system that combines Cortex-A and
Cortex-M processors [0].

These device trees contains the necessary bits to support the
Corstone 1000 FVP (Fixed Virtual Platform) [1] and the
FPGA MPS3 board Cortex-A35 implementation at Cortex-A35 host
side of this platform. [2]
