UPSTREAM: dm: video: Fix cache flushes

Content can come to screen via putc() and we cannot always rely on
updates ending with a puts(). This is the case with efi_console output
to vidconsole. Fixes corruption with Shell.efi.

With proportional fonts the vidconsole uclass cannot itself erase the
previous character. Provide an optional method so that the driver can
handle this operation.

video: Use fractional units for X coordinates

With anti-aliased fonts we need a more fine-grained horizontal position
than a single pixel. Characters can be positioned to start part-way through
a pixel, with anti-aliasing (greyscale edges) taking care of the visual
effect.

To cope with this, use fractional units (1/256 pixel) for horizontal
positions in the text console.

video: Name consoles by their number

We must use the console name in the 'stdout' variable to select the one
we want. At present the name is formed from the driver name with a suffix
indicating the rotation value.

It seems better to name them sequentially since this can be controlled by
driver order. So adjust the code to use 'vidconsole' for the first,
'vidconsole1' for the second, etc.

dm: video: Add a uclass for the text console

The existing LCD/video interface suffers from conflating the bitmap display
with text output on that display. As a result the implementation is more
complex than it needs to me.

We can support multiple text console drivers. Create a separate uclass to
support this, with its own API.
