[U-Boot] [PATCH v2 7/8] usb: rockchip: boost up write speed from 4MB/s to 15MB/s

[Alberto Panizzo]

Speedup transfers increasing the max chunk size.
Buffers are allocated with memalign thus developer is noticed when heap is
full and in current configuration a buffer allocation of 64K till now
is safe.
