Norman Feske 3bb894370a tool/run/load/fastboot: detect fastboot driver
Replace the unconditional sleep "until the board comes up" by the
detection of the fastboot-driver message. This shortens the total boot
time and reveals U-boots initial output, e.g., messages reporting
trouble with bringing up the fastboot driver.
