Joerg Wunsch 105cebb389 patch #9327: ft245r.c: add TPI support (patches 1-4) ...

Submitted by David Mosberger-Tang:

Optimize TPI programming speed by reducing number of USB reads.
Specifically, when writing to the FTDI chip (without needing the data
it accumulates), simply increment a count of how many bytes the next
read should ignore.  Thus, if there is one or more write followed by a
read, we only need to read from the device once.

Improves TPI programming speed by another factor of 2.
