balrog 02b373ad5d LSI53C895A: Handle empty SCRIPTS opcode (Justin Chevrier) 
Basically after each DMA transfer the Openserver driver would issue an
empty (0) SCRIPTS opcode. As the opcode is essentially a NOP it has no
second DWORD and therefore the DSP should only be incremented by 4 bytes
instead of the 8 bytes we currently do.

Here's a snippet of the log:

lsi_scsi: Data ready tag=0x100d9 len=16384
...
lsi_scsi: SCRIPTS dsp=068c5e50 opcode 01000400 arg 07a09000
lsi_scsi: DMA addr=0x07a09000 len=1024
lsi_scsi: SCRIPTS dsp=068c5e58 opcode 00000000 arg 01000400
lsi_scsi: Wrong phase got 1 expected 0

Note the 2nd DWORD after the empty opcode; the next opcode in the DMA
transfer sequence. As can be expected the address after that has the next
DMA address to use.

After the attached patch the DMA transfer is able to complete successfully:

lsi_scsi: SCRIPTS dsp=068c5e50 opcode 01000400 arg 07a0d000
lsi_scsi: DMA addr=0x07a0d000 len=1024
lsi_scsi: SCRIPTS dsp=068c5e5c opcode 01000400 arg 07a0d400
lsi_scsi: DMA addr=0x07a0d400 len=1024
...

Tested againsted Openserver 5.0.5 and Debian ARM.
