lynxpoint: Enable SerialIO clock in PCI mode
The clock gating register at offset 0x800 is managed by the
clock driver in the kernel when the devices are in ACPI mode.
When in PCI mode we should force enable the clock here.
When in ACPI mode or the device is disabled it should be put
in D3Hot state.
