dediprog: implement command spec for firmware >= 7.2.30
This adds support for the latest command spec for Dediprog SF100/SF600
programmers. Since we now have more than two protocols to
deal with the is_new_prot() function is replaced with protocol() which
returns an enum specifying which protocol is supported.
The latest spec (FW >= 7.2.30) updates read and write packets. It's
been tested on an SF600 using firmware 7.2.21 and SF600Plus using FW
7.2.30.
The latest command protocol has a few small but important changes:
- Read packets have two more bytes:
11: B4Addr: address len (3 or 4)
12: Dummy cycle /2
- Write packets have four more bytes:
11, 12: 16 HSBs of page size
13, 14: 16 LSBs of page size
(The spec seems to be mistaken, though, as 11 and 12 are actually
LSBs instead of HSBs)
