`struct console_font` is a UAPI structure, thus ideally should not be used for kernel internal abstraction. Remove some dummy .con_font_set, .con_font_default and .con_font_copy `struct consw` callback implementations, to make it cleaner. Patch "fbcon: Prevent global-out-of-bounds read in fbcon_copy_font()" depends on this patch, so Cc: stable.
