lib: Move fonts from drivers/video/console/ to lib/fonts/
Several drivers need font support independent of CONFIG_VT, cfr. commit 9cbce8d7e1dae0744ca4f68d62aa7de18196b6f4, "console/font: Refactor font support code selection logic"). Hence move the fonts and their support logic from drivers/video/console/ to its own library directory lib/fonts/. This also allows to limit processing of drivers/video/console/Makefile to CONFIG_VT=y again. [Kevin Hilman <khilman@linaro.org>: Update arch/arm/boot/compressed/Makefile] Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
