cjktty-patches

Patches from Gentoo-zh/linux-cjktty with minor changes.

• Starting with 5.10 the kernel config option CONFIG_FONT_16x16_CJK has been renamed to CONFIG_FONT_CJK_16x16.
• To have a larger font on high resolution screens, you probably want to apply 32x32 font data patch.
• The patch built-in fonts expect to work with 8x16 or 16x32 fonts. When changing to other font sizes, characters may not display correctly.
