Johan Hovold 3efeaff629 USB: pl2303: increase the bulk-out buffer size to 256 byte 
Increase the bulk-out buffer size from 64 to 256 byte.

This gives a significant increase in throughput already at 1Mbaud as well
as lowered CPU usage. The buffer is big enough to keep up also at 3Mbaud
(128b would not suffice).
