USB: EHCI pci-quirks.c: don't wait so long for BIOS handoff

Instead of waiting a painful 5000ms, quirk_usb_disable_ehci() now does a
1000ms loop to wait for the BIOS to acknowledge the handoff.

The five second delay is really quite irritating to have to deal with
every boot up, and I very seriously doubt any non-broken bios takes more
than a second to do the actual handoff.
