Commit 8a46828e623c ("soc/tegra: Register SoC device") added an initcall
to register the SoC device on Tegra. However, that code is unrestricted
and will run on all platforms, causing unwanted warnings.

Fix this by first checking that we're running on hardware that supports
the fuses block that we use to provide SoC information.

Allwinner A64's display engine claims the SRAM C section to work.

Add support for the A64 SRAM controller and the SRAM C section of it.
Signed-off-by: NIcenowy Zheng <icenowy@aosc.io>
Signed-off-by: NChen-Yu Tsai <wens@csie.org>

On some Allwinner SoCs, sometimes the value needed to write into the
register to claim SRAM is not equal to the value specified in the
device tree.

The device tree binding defines 0 as "mapped to CPU" and 1 as "mapped
to X device". This matches the value written to the configuration
register for the SRAM blocks currently supported. However, the not yet
supported VE SRAM block is claimed for the device by writing 0x7fffffff,
which is vastly different from the other blocks. On the A64, SRAM C is
claimed by the device by writing a 0, which is the opposite of the
current design.

Add a value remapping in sunxi_sram_func structure, and let the
sunxi_sram_of_parse function set the remapped register value.
This allows us to keep the convention currently used in the device tree
binding.

When claiming SRAM, if the base is set to an error, it means that the
SRAM controller has been probed, but failed to remap the controller
memory zone. If the base is zero, thus the SRAM controller should be not
probed at all, and it should return -EPROBE_DEFER. However, currently we
returned -EPROBE_DEFER in the former situation, and ignored the latter
situation (which will lead to the kernel to panic).

Fix the behavior on abnormal base address processing when claiming.
