Always building makes sure this code gets buildtested.
Calling this code already was guarded by
"if CONFIG(INTEL_TXT_LOGGING)".
Also build this in all stages as future code will use this in
bootblock.

With CBnT a digest needs to be made of the IBB, Initial BootBlock, in
this case the bootblock. After that a pointer to the BPM, Boot Policy
Manifest, containing the IBB digest needs to be added to the FIT
table.
If the fit table is inside the IBB, updating it with a pointer to the
BPM, would make the digest invalid.
The proper solution is to move the FIT table out of the bootblock.
The FIT table itself does not need to be covered by the digest as it
just contains pointers to structures that can by verified by the
hardware itself, such as microcode and ACMs (Authenticated Code
Modules).

They all operate on that file, so just add it globally.

Target added to INTERMEDIATE all operate on coreboot.pre, each modifying
the file in some way. When running them in parallel, coreboot.pre can be
read from and written to in parallel which can corrupt the result.
Add a function to create those rules that also adds existing
INTERMEDIATE targets to enforce an order (as established by evaluation
order of Makefile.inc files).
While at it, also add the addition to the PHONY target so we don't
forget it.

Provide necessary romstage hooks to allow unblocking the memory with
SCLEAN. Note that this is slow, and took four minutes with 4 GiB of RAM.
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.

SCLEAN has specific requirements and needs to run in early romstage,
since the DRAM would be locked when SCLEAN needs to be executed.

The Kconfig variables are used in the C code for cbfs file names but
not in the Makefiles adding them.

Add TXT ramstage driver:
* Show startup errors
* Check for TXT reset
* Check for Secrets-in-memory
* Add assembly for GETSEC instruction
* Check platform state if GETSEC instruction is supported
* Configure TXT memory regions
* Lock TXT
* Protect TSEG using DMA protected regions
* Place SINIT ACM
* Print information about ACMs
Extend the `security_clear_dram_request()` function:
* Clear all DRAM if secrets are in memory
Add a config so that the code gets build-tested. Since BIOS and SINIT
ACM binaries are not available, use the STM binary as a placeholder.
Tested on OCP Wedge100s and Facebook Watson
* Able to enter a Measured Launch Environment using SINIT ACM and TBOOT
* Secrets in Memory bit is set on ungraceful shutdown
* Memory is cleared after ungraceful shutdown
