scsi: wd33c93: Remove dead code related to the long-gone config WD33C93_PIO
The historical commit 5e018f7e60c9 ("Remove PC9800 support") from 2004 in
linux's history.git removed the config WD33C93_PIO to tweak the scsi
wd33c93 driver for the PC9800.
Some dead code in drivers/scsi/wd33c93.[ch] under an ifdef WD33C93_PIO
continued to remain in the repository until now.
Remove this dead code.
This issue was discovered with ./scripts/checkkconfigsymbols.py.
