mb/lenovo/x200: Add ThinkPad X301 as a variant 

It is similar to X200s, with U-series CPU, slightly different gpio
setup, no docking support, and no superio chip.

Tested:
    - CPU Core 2 Duo U9400
    - Slotted DIMM 4GiB*2 from samsung
    - Camera
    - pci-e slots
    - sata and usb2
    - libgfxinit-based graphic init
    - NVRAM options for North and South bridges
    - Sound
    - Thinkpad EC
    - S3
    - Linux 4.19.67-2 within Debian GNU/Linux stable, loaded from
      Linux payload (Heads) and Seabios.

TODO: repurpose and/or rename flag H8_DOCK_EARLY_INIT (introduced in
      CB:4294 ) for h8-using devices without a dock.

# Lenovo X301
## Disassembly Instructions
You must remove the following parts to access the SPI flash:
![X301 with WSON8 chip replaced with SOIC8 chip](x301_kb_removed.jpg)
* Battery pack
* Keyboard
Its [Hardware Maintenance Manual](https://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles_pdf/43y9441.pdf) can be used as a guidance of disassembly.
The WSON-8 flash chip (surrounded with red circle in the photo above,
already replaced with a SOIC-8 one) sits under a piece of insulating
tape. If solders between the chip and soldering pads fortunately
overflows beside the chip as tiny tin balls attached to soldering pads,
it will be possible to use a pomona 5250 clip to hold the chip, with
its metal tips just attached to tin balls, thus connecting the chip to
the programmer. Otherwise, it may be recommended to replace it with a
SOIC-8 one (you might need to add the chip to the IFD VSCC list), as
what is done in the photo.
The vendor IFD VSCC list contains:
-MACRONIX_MX25L6405 (0xc2, 0x2017)
-WINBOND_NEX_W25X64 (0xef, 0x3017)
-ATMEL_AT25DF641 (0x1f, 0x4800)
```eval_rst
:doc:`../../flash_tutorial/ext_power`
```
Tested:
- CPU Core 2 Duo U9400
- Slotted DIMM 4GiB*2 from samsung
- Camera
- pci-e slots
- sata and usb2
- libgfxinit-based graphic init
- NVRAM options for North and South bridges
- Sound
- Thinkpad EC
