[U-Boot] [PATCH 6/7] usb: rockchip: be quiet on serial port while transferring data

[Alberto Panizzo]

While downloading or uploading megabytes of data we had thousands of
dummy lines like:

transfer 0x10000 bytes done
OR
Uploading 0x1000 bytes

even on non-debug builds. This because transfers are chunked and
code running on target does not have any clue about when the current
chunk is the last one.
