drivers/jtag: rewrite usb_blaster driver
Rewrite the Altera USB Blaster dongle driver :
- make extensive use of byte-shift mode, to improve JTAG
speed.
This is the main reason of the rewrite. It improves the
memory dumps with a factor 3 at least, and upload 100
times, from 1 kBytes/sec to 100 kBytes/sec with a
USB-Blaster connected to an Altera Virtual JTAG TAP +
OpenRISC CPU.
- split the low level API part (between FTDI and FTD2xx)
from core driver, so that in the future, if both libftdi
and ftd2xx can coexist, the driver will be able to switch
dynamically from one access to the other.
