dalao 56a25a98db mainboard/lenovo: Use the original hardware ids for keyboard/pointing
Currently coreboot is using the compatible ID PNP0303 for all keyboards
and PNP0F13 for all pointing devices, which causes some problems. On
Windows, the touchpad driver can't be automatically matched and
installed through Windows Update. On Linux, there are some strange
issues. So it's better to use the original hardware IDs for each model.
The hardware IDs for the following models can be found By searching for
dmesg logs on vendor BIOS:

Chris Morgan 5e5e789f9b nb/intel/haswell/peg: Add PEG driver stub
This is a port of https://review.coreboot.org/c/coreboot/+/22337 to the
Haswell northbridge.  This code is necessary to support the dGPU of the
t440p. Code was cut and pasted from Sandy Bridge with vendor IDs updated
to the correct Haswell values.  Tested on t440p with dGPU on Ubuntu
18.04.4 with 5.3.0-28 kernel. Without patches dmesg reports Nouveau is
unable to read the VBIOS of the dGPU as it has an invalid checksum (I
checked that the ROM in CBFS is correct). With this patch DRM works
correctly with both the Nouveau driver and the Nvidia proprietary
driver. Windows 10 1909 also tested but generates bluescreen once GPU
driver is loaded.

Maccraft 0cd098e4e4 mb/lenovo/{t60,r60}: Add ThinkPad R60 support as variant board
- This port should be Reclaim Your Freedom compliant
  (not certified yet).
- Untested on boards with external Radeon graphics adapter.
- Some columns on the left-most side of display are completely
  black on 1400x1050 IPS display[1]. Display works fine on Linux.
  I don't know why it appears like that. So far it has been observed
  only with native graphics initialization.
- Only GRUB2 and SeaBIOS payloads tested for now.
- 2504 docking station USB doesn't work under Linux.
  Can detect pendrive in GRUB2 payload.
- Sometimes it takes 20s of "pretending it's powered off" to run
  coreboot code. Issue is payload agnostic.
  Probably caused by missing one capacitor on my unit.

Bill XIE 012ef7735d mainboard/lenovo/t430s: Add ThinkPad T431s as a variant
The code is based on autoport and that for T430s

Tested:
- CPU i5-3337U
- Slotted DIMM 2GiB
- Soldered RAM 4GiB from samsung (There may be more models here)
- Camera
- pci-e and usb2 on M.2 slot with A key for wlan
- sata and usb2  (no superspeed components) on M.2 slot with B key for wwan
- On board SDHCI connected to pci-e
- USB3 ports
- libgfxinit-based graphic init
- NVRAM options for North and South bridges
- Sound
- Thinkpad EC
- S3
- TPM1 on LPC
- EHCI debug on SSP2 (USB3 port on the left)
- Linux 4.9.110-3 within Debian GNU/Linux stable, loaded from
  Linux payload (Heads), Seabios may also work.

Not tested:
- Fingerprint reader on USB2 (not present on mine)
- Keyboard backlight (not present on mine)
- "sticky_fn" flag in nvram

Not implemented yet:
- Fn locking in nvram (may not be identical to "sticky_fn")
- C-based native graphic init (since T431s has eDP instead of LVDS)
- Detecting the model of Soldered RAM at runtime, and loading the
  corresponding SPD datum (3 observed) from CBFS (the mechanism may be
  similar to that on x1_carbon_gen1 and s230u, but I do not know how
  to find gpio ports for that, and SPD data stored in vendor firmware.)

Also remove the trailing colon, because it's unnecessary in a heading.
