x86/Kconfig: Make EFI select UCS2_STRING
The commit "efi: Distinguish between "remaining space" and actually used
space" added usage of ucs2_*() functions to arch/x86/platform/efi/efi.c,
but the only thing which selected UCS2_STRING was EFI_VARS, which is
technically optional and can be built as a module.

This enables the kernel to use EFI runtime services that are
available (such as the EFI variable services).
