Device ID collision in amd_flash.c

[Jonas Holmberg]

The (obsolete) AMD NOR-flash driver has an "probe-table-entry" for 
AM29BDS643D that happens to match AM29DL640G as well, even though they  
have different block/sector-layouts.

I think the problem is that AMD is assigning device-IDs of more than 
16-bits.  Anyhow, both AM29BDS643D and AM29DL640G supports CFI, so I 
would like to remove support for them in amd_flash.c (patch below) to 
avoid problems.

OK to commit?

PS. Would this patch ever find it's way into Linux 2.4 or just Linux 
2.6?
