patch proposal

Current SST 39VFxxx driver use command code "0x30" to erase a block, but it
must use the command code "0x50" instead.
In fact, according to the SST 39VF640 datasheet, Sector-Erase (0x50) erase
2Kword while Block-Erase (0x30) erase 32Kword.

Attached a patch against the CVS head which use the 0x50 op-code and add
support for 39VF6401B and 39VF6402B.
