regulator: make the dummy regulator's print_constraint more helpful

Browse source 
This prevents the output of just

	dummy:

in the boot log. Now it says:

	regulator-dummy: no parameters

which at least doesn't make it look like an accidental printk and also doesn't
only use "dummy" which could mean anything.
