CHROMIUM: add scsi_write to SCSI driver.
Verified boot requires writing to GPT attributes (success / tries), so we need
to implement *_write.
"scsi write" command is also added to console for testing.
BUG=chrome-os-partner:6258
TEST=(1) Modified GPT to trigger VBOOT updating GPT, and verified
GPT changed successfully (by firmware) after reboot
(2) ext2load usb 1:1 10000000 /part2.bin # load kernel partition dump
scsi write 10000000 5000 5000 # write into kernel partition in #2
