Subject: [PATCH v2 00/15] Cedrus H5 and A64 support with A33 and H3 updates

This series adds support for the Allwinner H5 and A64 platforms to the
cedrus stateless video codec driver, with minor updates to the A33 and
H3 platforms.

It requires changes to the SRAM driver bindings and driver, to properly
support the H5 and the A64 C1 SRAM section. Because a H5-specific
system-control node is introduced, the dummy syscon node that was shared
between the H3 and H5 is removed in favor of each platform-specific node.
A few fixes are included to ensure that the EMAC clock configuration
register is still accessible through the sunxi SRAM driver (instead of the
dummy syscon node, that was there for this purpose) on the H3 and H5.

The reserved memory nodes for the A33 and H3 are also removed in this
series, since they are not actually necessary.

Changes since v1:
* Removed the reserved-memory nodes for the A64 and H5;
* Removed the reserved-memory nodes for the A33 and H3;
* Corrected the SRAM bases and sizes to the best of our knowledge;
* Dropped cosmetic dt changes already included in the sunxi tree.
