Some devices, such as cameras, can implement a physical switch to
disable the input on demand. Think of it like the typical privacy
sticker on the notebooks, but more elegant.
In order to notify the system about the status this feature, a GPIO is
typically used.
The map between a GPIO and the feature is done via ACPI, the same way as
the reset_gpio works.
This patch implements an extra field for the described privacy gpio.
This gpio does not require any extra handling from the power management.

Production Volteer devices have Cr50 TPM connected via SPI, depending on
Cr50 firmware version it may or may not support long enough interrupt
pulses for the SoC to safely be able to enable lowest power mode.
Some reworked Volteer devices have had the Cr50 (Haven) TPM replaced
with Dauntless, communicating via I2C. The I2C drivers do not support
being accessed early in ramstage, before chip init and memory
mapping, (tlcl_lib_init() will halt with an error finding the I2C
controller base address.)
Since the Dauntless device under development can be made to support
longer interrupts, or a completely new interrupt signalling mode, there
is no need to try to go through the same discovery as is done via SPI.
This CL will skip the discovery, enabling the S0i3.4 sleep mode in all
cases, on the reworked test devices.

Register at offset 0x64 is DCAP2, and offset 0x68 is DCTL2.
However, current code doesn't account for this. The result is that
register 64h[19:18] = 2 and 68h[14:13] = 0, which means the hardware is
OBFF-capable but support is disabled, which makes no sense. Given that
reference code and Broadwell both disable OBFF, disable it here too.

Testing shows that these registers are backwards. Use the definitions
from Broadwell instead. All affected boards use the same value for both.

For all these southbridges, the lower nibble of PCICMD is read-only.
Tested on Asrock B85M Pro4 (Lynxpoint-H), LPC's PCICMD does not change.
