All our QOM users provides an input clock. In order to avoid
avoid future machines added without clock, display a warning.
User-mode emulation use the CP0 timer with the RDHWR instruction
(see commit cdfcad788394) so keep using the fixed 200 MHz clock
without diplaying any warning. Only display it in system-mode
emulation.
