video: Add a default TrueType font

At present it is possible to enable TrueType support but not include any
fonts. This results in a blank display. Select Nimbus as the default font
to avoid this.

video: Add the Cantoraone decorative font

This font is a little more ornate than normal. Example uses are on security
screens where a feeling of formality is required.

This can be used when a a friendly 'hand-writing' font is needed. It helps
to make the device feel familiar.

video: Add the AnkaCoder mono-spaced font

This can be used when a mono-space font is needed, but the console font
is too small (such as with high-DPI displays).

video: Add a console driver that uses TrueType fonts

The existing 8x16 font is adequate for most purposes. It is small and fast.
However for boot screens where information must be presented to the user,
the console font is not ideal. Common requirements are larger and
better-looking fonts.

This console driver can use TrueType fonts built into U-Boot, and render
them at any size. This can be used in scripts to place text as needed on
the display.

This driver is not really designed to operate with the command line. Much
of U-Boot expects a fixed-width font. But to keep things working correctly,
rudimentary support for the console is provided. The main missing feature is
support for command-line editing.
