dediprog: Use more general 4BA write mode for newer protocols

We used to send the specific WRITE_MODE_4B_ADDR_256B_PAGE_PGM_0x12
command combined with the 0x12 JEDEC SPI opcode. This doesn't work
on newer programmers anymore,  and it turns out that `dpcmd' pairs
it only in special cases with an SF100.

`dpcmd' suggests that for SF600 and newer,  the more generic write
mode (WRITE_MODE_4B_ADDR_256B_PAGE_PGM) works with the 0x12 opcode
too. So using that for protocal version 3 seems safe.

Tested with "SF600PG2. V:01.01.012 HW:01.00".
