This patchset adds Spreadtrum's Sharkl64 support in arm64 device tree.

Changes from v7:
	- Added Mark Rutland's Acked-by
	- Rebased v4.0-rc1

Changes from v6:
	- Setted stdout-path with "serial1:115200n8"

Changes from v5:
	- Added maintenance interrupt for gic
	- Removed reg property from 'soc' and 'apb' nodes

Applied both to next/arm64.

I had some trouble applying the patches because of broken end-of-line

Sorry for that, I have found the reason about smpt server, I'll avoid
the same problem in the future.
