USB: cxacru: firmware writes on OHCI are slow, log progress
Firmware writing takes 256ms per 4KB with OHCI, which
is very slow compared to 7ms per 4KB with UHCI.
Until I have access to a hardware USB analyser it may
not be possible to determine why this happens.
Instead of appearing to do nothing, log progress when
writing firmware and then log the ATM device information
when finished. Remove an unnecessary 4 second delay.
