mb/lenovo/r500: Add mainboard

Tested:
- Ethernet NIC
- Wifi RFKill
- USB
- LVDS, VGA with libgfxinit
- Booting with dock attached (COM1)
- Keyboard, trackpoint
- SeaBIOS 1.12
- S3 resume
- Tested in descriptor mode, with vendor FD and ME
- Add VBT to ACPI OPregion

Untested:
- SATA (likely works)
- Trackpad (my cable is broken, likely works)
- Displayport (likely works)
- Descriptorless mode
- DVD drive
- Extra battery
- model with ATI GPU

Does not work:
- Dock hotplug
- Quad core CPU (hangs during AP init, probably needs hardware mod)
- Hotplugging the expresscard slot (works with 'echo 1 | sudo tee
/sys/bus/pci/rescan')

TODO:
- proper dock support
- documentation

note: This board was hard to flash, I had to desolder the flash.

TESTED: on a R500 with an Intel iGPU, SeaBIOS 1.12, Debian 9,
Linux 4.9 from USB
