At present this feature is enabled in SPL if a bloblist is available.
Some platforms may not want to use this, so add an option to allow the
feature to be disabled.
Note that the feature unfortunately only fills in part of the
video-handoff information, so causes failures on x86 platforms. For now,
disable it there.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

For PCI video devices that are not mentioned in the devicetree, U-Boot
does not bind a driver before relocation, since PCI is not fully probed
at that point. Furthermore it is possible for the video device to be on
a secondary bus which is not even scanned.
This is fine if the framebuffer is allocated in fixed memory, as it
normally is on x86. But when using this as a copy framebuffer, we also
need U-Boot to allocate its own cached framebuffer for working in. Since
the video driver is never bound before relocation, the framebuffer size
is never set and U-Boot does no allocation.
Add a new CONFIG option to reserve 16MB of memory for this eventuality.
This allows vesa devices to use the copy framebuffer.

Some architectures use a cached framebuffer and flush the cache as needed
so that changes are visible. This is supported by U-Boot.
However x86 uses an uncached framebuffer with a 'write-combining' feature
to speed up writes. Reads are permitted but they are extremely expensive.
Unfortunately, reading from the frame buffer is quite common, e.g. to
scroll it. This makes scrolling very slow.
Add a new feature which supports copying modified parts of the frame
buffer to the uncached hardware buffer. This speeds up scrolling by at
least 10x on x86 so the extra complexity cost seems worth it.
As a starting point, add the Kconfig, update the video structures to keep
track of the buffer and add a function to do the copy.
