i2c: i801: Hide Intel Birch Stream SoC TCO WDT

commit 664596bd98bb251dd417dfd3f9b615b661e1e44a upstream.

Hide the Intel Birch Stream SoC TCO WDT feature since it was removed.

On platforms with PCH TCO WDT, this redundant device might be rendering
errors like this:

[   28.144542] sysfs: cannot create duplicate filename '/bus/platform/devices/iTCO_wdt'
