[PATCH 1/2] mfd: syscon: make mfd/syscon.h header self-contained

[Ahmad Fatoum]

From: Ahmad Fatoum <a.fatoum at barebox.org>

Including the header in new files can currently break the build if
suitable headers aren't included beforehand.

Make it self-contained and while at it, switch over to SPDX.
