efi_loader: initialize the RNG protocol after the TCC2
Due to U-Boot's lazy binding the RNG presented by the TCG is not available
until the EFI_TCG2 protocol has been initialized. Since the TPM has a
built-in RNG device we can use for the OS randomization, move the RNG
protocol installation after the TCG.
