efi/libstub/arm/arm64: Disable debug prints on 'quiet' cmdline arg
The EFI stub currently prints a number of diagnostic messages that do not carry a lot of information. Since these prints are not controlled by 'loglevel' or other command line parameters, and since they appear on the EFI framebuffer as well (if enabled), it would be nice if we could turn them off. So let's add support for the 'quiet' command line parameter in the stub, and disable the non-error prints if it is passed.
