Set the default state of the TCSS PCIe RP0 to hidden so that coreboot
does not allocate resources to this hotplug root port. The default
behavior on the reference design is that there is only one USB4 port
attached to port C1 while port C0 is only a USB3 port.
Meanwhile the Voxel and Terrador variants do have USB4 on both C0 and
C1 ports, so these boards change the default to 'on' so that coreboot
does allocate resources for the hotplug port.

There is an issue with the storage device being mis-detected on exit

To work around this read the RX state of the pin and apply the IOSSTATE

Windows does not comply with the Low Power Idle S0 specification and
crashes with an `INTERNAL_POWER_ERROR` bluescreen when function 1, does
not return at least one device constraint, even when function 1 is
announced as being not available by the enum function. Returning an
empty package does not work.
At least the following Windows versions were verified to be affected:
- Windows 8.1 x64, release 6.3.9600
- Windoes 10 x64, version 1809, build 17763.379
- Windows 10 x64, version 1903, build 18362.53
- Windows 10 x64, version 2004, build 19041.508
- Windows 10 x64, version 20H2 / 2009, build 19042.450
To make Windows work on S0ix-enabled boards, return a dummy constraint
package with a disabled dummy device.
Since the device constraints are only used for debugging low power
states in Linux and probably also in Windows, there shouldn't be any
negative effect to S0ix. Real device constraint entries could be added
at a later point, if needed.
Note: to fully prevent the BSOD mentioned above the LPIT table is
required on Windows, too. The patch for this is WIP, see CB:32350.
If you want to test this, you need to applie the whole ACPI patch
series including the hacky LPIT test implementation from CB:47242:
