[PATCH v5 11/22] ARM: sun5i: Add support for the C1 SRAM region with the SRAM controller

[Paul Kocialkowski <paul.kocialkowski-LDxbnhwyfcJBDgjK7y7TUQ@public.gmane.org>]

From: Maxime Ripard <maxime.ripard-LDxbnhwyfcJBDgjK7y7TUQ@public.gmane.org>

This adds support for the C1 SRAM region (to be used with the SRAM
controller driver) for sun5i-based platforms. The region is shared
between the Video Engine and the CPU.
