Re-worked sed1520 driver:
- Add 68-familiy style interface support and make it configurable. - Make delay configurable. - Correct swapped display halves. - Resurrect vBar / hBar functions. - Fix icon definitions and modify set_char for common data format.

was not successful. I suspect that (as the E# line is used as /RD line in

80-style mode) the wiring resulted in reading from one chip while writing to

the other at the same time and the data bus got fuzzed.</para>
