i2c: piix4: Fix request_region size
[ Upstream commit f43128c75202f29ee71aa83e6c320a911137c189 ]
Since '701dc207bf55 ("i2c: piix4: Avoid race conditions with IMC")' we
are using the SMBSLVCNT register at offset 0x8. We need to request it.
Fixes: 701dc207bf55 ("i2c: piix4: Avoid race conditions with IMC")
