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

Provide necessary romstage hooks to allow unblocking the memory with

Tested on Asrock B85M Pro4 with tboot. When Linux has tboot support
compiled in, booting as well as S3 suspend and resume are functional.
However, SINIT will TXT reset when the iGPU is enabled, and using a dGPU
will result in DMAR-related problems as soon as the IOMMU is enabled.
However, SCLEAN seems to hang sometimes. This may be because the AP
initialization that reference code does before SCLEAN is missing, but
the ACM is still able to unblock the memory. Considering that SCLEAN is
critical to recover an otherwise-bricked platform but is hardly ever
necessary, prefer having a partially-working solution over none at all.
