dt-bindings: display: panel: mipi-dbi-spi: add Saef SF-TC154B

The Saef SF-TC154B is a 1.54 inch 240x240 square panel with a MIPI DBI
compatible interface. The panel is used on the Anbernic RG-Nano
handheld gaming device.

The initialization of the panel requires a firmware binary which can
be made with the mipi-dbi-cmd[1] tool. The command sequence needed
can be found in both source[2] and binary form[3].
