[U-Boot] [PATCH v2 4/5] efi_loader: make Unicode collation protocol customizable

The Unicode collation protocol is not needed for EBBR compliance. So let's
make it a customizable option.

The Unicode capitalization table is only needed by this protocol. So let it
depend on the Unicode collation protocol.
