Joerg Wunsch 49e5f2451c patch #9328: ft245r.c: add TPI support (patches 5-7) 
Submitted by David Mosberger-Tang:
* ft245r.c (ft245r_set_bitclock): add workaround for
FT245 hardware bugs in bitclock setting

Correct baud rate calculation (multiplying with factor of 2 was wrong)
and add compile-time workaround for FTDI chips suffering for the
variable pulse-width errata.  The workaround entails always running
the chip at 3MHz and stuffing the channel with repeated bytes to
achieve the desired baudrate.

This has no effect on programming speed.  Note, however, that now a
baudrate option -b750000 has to be used to achieve maximum speed.

(Option enabled by default now.)
