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.
