History
dbrownell 817ea3f4e4 Update FT2232 driver so that it reliably enters TAP_RESET. 
When the OpenOCD server starts up it records its state as TAP_RESET,
even though it could be anything.  Then when it starts to examine
the scan chain, it calls jtag_add_tlr() which sees it doesn't have
any work to do, and so it does nothing.  This can make the next
operations fail because they start from the wrong TAP state...

Instead of caring about the current recorded state, always enter
TAP_RESET by forcing five clocks with TMS high.

(NOTE:  it seems most other JTAG adapter drivers have this same bug.)
