Julius Werner 52e3f449ac libpayload: Increase USB EHCI transfer timeout
The EHCI driver defines a maximum transfer timeout of two seconds. The
comments state that during tests the maximum amount of required transfer
time was for the SCSI TEST_UNIT_READY command on certain devices. We
have now observed a USB device (Patriot Memory 13fe:3100) that can NAK
this command for slightly more than two seconds. It will also completely
fail if the timeout hits, since it gets confused by the subsequent CSW
retry/recovery mechanism and starts producing babble errors. This patch
increases the timeout to three seconds to circumvent this problem.

To test, boot a Falco from a red-black RageXT USB stick.
