video: Add support for copying to a hardware 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.

The functions in this file do similar things but not always in the same
way. To make the code easier to read and compare, use a separate 'linenum'
variable in every function. This is then multiplied by the line length to
get the offset within the frame buffer to modify. Also use an 'x' variable
to hold the pixel position within that line. This is multipled by the
pixel size and added to the offset.

Also move the pbytes declaration up a little with the other long lines.

A side effect of splitting out these variables is that they are promoted
to int, i.e. a signed type, from the unsigned short used in the
vidconsole_priv struct. This would be necessary should any of the

Calculate the SDRAM size from DDR capacity register registers instead
of using hard-coded value. This is quite useful to get correct size
on differnt boards based on Actions OWL family of SoCs (S700 and S900).

There is no documentation available that talks about DDR registers, and

arm64: issue ISB after updating system registers

ARM Architecture reference manual clearly states that PE pipeline
should be flushed after changes to some system registers. Refer to
paragraph "B2.3.5 Memory Barriers" at page B2-92 of "Arm Architecture
Reference Manual ARMv8 for ARMv8-A Architecture Profile" (ARM DDI
0487B.a).

Failing to issue instruction synchronization barrier can lead to
spurious errors, like synchronous exception when accessing FPU
registers. This is very prominent on CPUs with long instruction
pipeline, like ARM Cortex A72.

This change fixes the following U-Boot panic:
