usb: reduce kernel log spam on driver registration

Drivers are typically supposed to be quiet unless they are actually
probed, but for some reason, USB host controllers seem to be exempt from
this rule, and happily broadcast their existence into the kernel log at
boot even if the hardware in question is nowhere to be found.

Let's fix that, and remove these pr_info() calls.
