mb/lenovo: Add ThinkPad W530 support

Tested and working:
  - Wi-Fi
  - Ethernet
  - WWAN ? (interface is created in linux, didn't actually test it, should work)
  - Bluetooth
  - Speakers
  - Internal mic
  - SD card reader
  - Suspend and resume
  - Keyboard, touchpad, trackpoint
  - Fan
  - Webcam
  - 4 RAM slots
  - All USB ports
  - mSATA
  - VGA ROM (FIXME: black screen after resume from s3)
  - Native graphics initialization (FIXME: probably incorrect panel frequency, etc. in GRUB; in linux everything's fine incl. resume from s3)
  - libgfxinit
  - GRUB payload
  - SeaBIOS payload
  - Internal flashing using flashrom

Not tested yet:
  - Fingerprint reader
  - Colorimeter
  - Smart card reader
  - Docking station
  - VGA output
  - Optical disc drive
  - Discrete graphics

TODO:
  - Test BDC detection
