i2c: i801: Restore configuration at shutdown commit f7f6d915a10f7f2bce17e3b1b7d3376562395a28 upstream. On some systems, the BIOS expects certain SMBus register values to match the hardware defaults. Restore these configuration registers at shutdown time to avoid confusing the BIOS. This avoids hard-locking such systems upon reboot.
