The original aligned_buffer usage: a) Uselessly copied data into the aligned buffer even for IN transactions. Fix this my making the copy conditional. b) Always programmed the HW to transfer to/from the start of the aligned buffer. This worked fine for OUT transactions since the memcpy copied the OUT data to this location too. However, for large IN transactions, since the copy from the aligned buffer to the "client" buffer was deferred until after all chunks were transferred. it resulted in each chunk's transfer over-writing the data for the first transfer. Fix this by copying IN data as soon as it's received.

Applied to u-boot-usb/topic/dwc2, thanks. I would like to see more testing from others if possible, otherwise this will go in after 2015.04 if you're fine with that.
Best regards, Marek Vasut
