Subject: [PATCH] Drop doslowusb and noslowusb boot parameters.

scandelay=<secs> should be always preferred. Moreover, nowadays
automatically sleeping waiting for USB storage to come up in
the way we were used to do it doesn't work as one expects, because
USB is very common and USB storage devices are very likely to be
present on a system.
Furthermore, the initialization code after setup_slowusb is already
waiting for devices to come up.
