[PATCH] USB: Emagic USB firmware loading fixes

It's become apparent as machines get faster that the emagic kernel firmware
loaders (based on the ezusb loader) have a reset race.  a 400MHz TiBook
never tripped it, but a 2GHz Pentium M seems to hit it about 30% of the
time.  The bug is seen as a hung USB box and the kernel error:

drivers/usb/misc/emi62.c: emi62_load_firmware - error loading firmware:
error = -110

The patch below inserts a delay after deasserting reset to allow the box to
settle before a new command is issued.  This affects only device startup.
