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

Commit c1dc2d5e68 (mb/lenovo/t60: Switch to override tree) converted
these boards to override trees, but some device nodes were missed.
Said nodes are essential, as `chip` configuration data is always tied
to device nodes. The resulting `static.c` contained multiple copies
of the `chip` configuration structs, but the wrong ones were hooked up.
The therefore missing configuration of the clockgen led to general
instability, especially with SMP under Linux (probably due to the
attempt to enter lower C states on an idle core). Passing `maxcpus=1`
to the Linux kernel served as a workaround.

Current code uses CPUID leaf 0x1, EBX bits 16:23 to determine number for

real number of cores. According to SDM vol 2A, it stays for "maximum
number of addressable IDs for logical processors in this physical
package". This does not seem to take into account fusing of giving
processor.
The new code determines 'core count' by dividing thread-level cpus by
reported logical cores. This seems to be the only way to arrive
to number of cores as it is reported in official CPU datasheet.

The BUC register is actually only 8 bits wide and setting bit 5
(disabling GbE) is already done by generic code.

Only set LPC decode bits that the generic PCH code doesn't set yet. And
don't enable the IOAPIC, which is already done by generic code.

This bit is used to indicate xHCI routing across reboots. If anything,
coreboot should act on it, not set it during boot. ASL code would be
supposed to set it.

The generic PCH code already enables a superset of LPC decoding. Move
UART setup to bootblock_mainboard_early_init() where it is expected.
Last but not least, remove an odd write to BUCs (RCBA+0x3414) and
beyond, as it's an 8-bit register and shouldn't be bluntly zeroed.

mainboard_pch_lpc_setup() and mainboard_late_rcba_config() did 4
things here on top of the generic PCH code:
1. Enabling LPC decoding for gameports. It seems unlikely
that anything is using these ports and there is no code
to support gameports.
2. Decoding of COM3 instead of COM2. What COM?
3. Premature locking of ETR3/global reset. Bad idea.
4. Disabling the GbE port in BUC. Already done by PCH code.
