While drivers/firmware/efi/ won't be entered during the build phase if CONFIG_EFI=n, and drivers/firmware/efi/earlycon.c itself thus won't be built, enabling EFI_EARLYCON does force-enable CONFIG_FONT_SUPPORT and CONFIG_ARCH_USE_MEMREMAP_PROT, and CONFIG_FONT_8x16, which is undesirable. Fix this by making CONFIG_EFI_EARLYCON depend on CONFIG_EFI. This reduces kernel size on headless systems by more than 4 KiB.
