Your DSDT contains:
OperationRegion (PHO, SystemIO, 0x04BC, One)
We won't touch the same region because of the risk of races between the
firmware and the kernel. Boot with acpi_enforce_resources=lax if you
think it's safe. Alternatively, if the i2c driver doesn't need the 0x4bc
address, fix it not to request it.
