Subject[PATCH 3/3] LoongArch: Always select EFI
Date
Building loongarch:allnoconfig or loongarch:tinyconfig fails with the
following error.

loongarch64-linux-gnu-ld: arch/loongarch/kernel/env.o: in function `init_environ':
env.c:(.init.text+0xe4): undefined reference to `efi'
loongarch64-linux-gnu-ld: env.c:(.init.text+0xe8): undefined reference to `efi'

loongarch64-linux-gnu-ld: env.c:(.init.text+0x11c): undefined reference to `efi_memmap_init_early'
loongarch64-linux-gnu-ld: arch/loongarch/kernel/setup.o: in function `platform_init':
setup.c:(.init.text+0x228): undefined reference to `efi_init'
loongarch64-linux-gnu-ld: setup.c:(.init.text+0x250): undefined reference to `efi_runtime_init'
loongarch64-linux-gnu-ld: arch/loongarch/kernel/mem.o: in function `memblock_init':
mem.c:(.init.text+0x24): undefined reference to `efi'
loongarch64-linux-gnu-ld: mem.c:(.init.text+0x28): undefined reference to `efi'
loongarch64-linux-gnu-ld: mem.c:(.init.text+0x28): undefined reference to `efi'

Since it is mandatory, auto-select EFI support to fix the error. Drop the
EFI Kconfig help message since it is not needed.
